Wrt. Praetorium: Sorry, but what kind of argument is that? You could say exactly the same about Natural Philosophy: You already get science from campuses, does that make Natural Philosophy useless? Eh ... It's not like I'm going to give a big defensive speak for Praetorium, because I agree the card is (too) weak, but logically I just don't think your argument holds. For the record I've use Praetorium plenty of times when warring and being in a dark age. Often slotting in Praetorium along with the card that gives loyalty from a garrisoned unit is enough to make a city go from revolting in, say 4-5 turns, to instead revolting in 8-10 turns. That's pretty significant, because in that time span, it's much more likely that you'll conquer another city, and/or repairing the monument, which may then turn your loyalty into green.
