Why? You only see comets when they're near the sun. Oort cloud objects are on highly eliptical orbits with incredibly long orbital periods and only spend a tiny fraction of that orbit anywhere near the Sun. Any more frequent visitors will also be burned up faster so there are less likely to be any of those left. Basically the longer you wait, the less likely you are to see them in the sky.

The Oort Cloud is too far to be seen with current telescopes, so it hasn't been directly seen or discovered. However, it is scientists' best guess about where long-period comets come from. Astronomers have studied several comets believed to have come from this distant region of our solar system.
The simplest explanation is comets formed with the planets and were ejected into long period orbits - and not trillions or billions.
Tempel 1 revealed itself to be made of water ice and gas, carbonates, polyaromatic hydrocarbons, silicates, sulfides and other elements.
This mix of components does not match current models of comet dust. Some of the minerals detected require temperatures between 1,100 and 1,400 degrees Kelvin--only found as close to the sun as Mercury--as well as volatile gases such as methane that only remain stable at temperatures below 100 K. This means that there must have been some form of mixing over large distances going on in the nebula that gave birth to the sun billions of years ago.
The spectra also hint that water must have been abundant in the area where the comet formed and that Tempel 1 is not as carbon-rich as some of its peers; carbon-based materials appear to make up only 20 percent of this comet compared to as much as 50 percent of others. Nevertheless, the material in Tempel 1 matches that ejected by Comet Hale-Bopp in 1995 and that means that these comets formed in broadly similar ways, the researchers argue.

I think that means comets (these anyway) formed close to the sun or from larger bodies that had experienced significant heat. We've had 4.6 billion years for Oort Cloud comets to be nudged into orbits approaching the sun. Not all of them would survive of course, but with a reservoir possibly numbering in the trillions I'd expect much more activity. And comet cores are rocky so they dont burn up, they just look like asteroids when they lose their volatiles. And then there's the retrograde problem, roughly half of long period comets orbit the sun clockwise. That suggests interactions with large planets put them into long period orbits.
Can you describe exactly how you think Pluto is associated with Saturn? As established 2 years ago, all you seem to be saying is that when Pluto is in opposition to Saturn, AND this coincides with when Pluto is at aphelion (I think), then Pluto lies roughly in Saturn's equitorial plane (but many, many AU away). This doesn't seem to be aything other than a coincidence (such as, again, saying Polaris is "associated" with Earth). But really I want some sort of description of how a moon that is in orbit around a parent planet can be "perturbed" in such a way that it ends up in a completely different orbit around the Sun, 30 AU away. It would have to be something like... Pluto being in orbit around Saturn when it (gravitationally?) interracts with some other massive object that imparts it with a significant amount of kinetic energy, enought to shift it a further 30 AU away from the Sun. Then when it gets out there, it would have to have a similar interraction with another massive object to then push it into a completely different orbit that now no longer goes anywhere near Saturn's orbit and isn't related to it at all, other than Pluto's orbital plane and Saturn's equatorial plane intersect in a particular way that you find interesting.
If a Saturnian moon was ejected from an equatorial orbit, it would begin orbiting the sun once the energy driving the ejection was overcome by the sun's gravity. But it would still line up with the equatorial plane of its parent planet, Pluto does just that. Based on that scenario I'd expect more bodies to lie on that plane, like a trail of bread crumbs leading us back to Saturn. The rings of Saturn point to Pluto at its perihelion (closest approach). And I dont think its a coincidence Pluto's nearest and furthest point creates a 1:2 ratio when Saturn's distance from the sun is subtracted from Pluto's orbit.
IIRC most of the Oort cloud objects don't even get near the Sun, comets are the ones that are pulled for whatever reason - I think the idea is that it's most often gravitational interaction with stars neighboring the Sun - into very high-eccentricity orbits with part of the orbital path being quite close to the sun.
If a star passed nearby I'd expect a shower of comets to flood the system and I'd expect for a bunch of them to survive long enough on similar orbits to be seen by us. Or if not seen, detected by their craters.
