Te only protection creators need is recognition, and that is covered under the laws against fraud and misrepresentation. the so-called "intellectual property" laws were always about rent-seeking and (sometimes) also censorship on the cheap for the state.
The point is - mutual competition is the determining force of the economy and with that to a large degree of society. And as long as that is so, the abolishment of intellectual property is madness.
But you are welcome to propose alternative economic models which allow for a lack of intellectual property.
Predictably, I'm going to absolutely disagree with this. I won't even argue about the competition as the main driving force bit, I'll accept it as a given for the purpose of this discussion. The obvious question remains:why are monopoly rights on ideas and technology necessary in that context? Isn't competition supposed to produce better results under a free exchange of ideas, through the unfettered use of new technology?
What you fear is that one company would develop something, and another copy it. I'll say:
that would be a good thing! Not to copy a good thing, a good process or a good product, is wasteful. Suppose a company now invented "the wheel"; reinventing the wheel in a thousand different ways just to evade a patent on the wheel is wasteful. Let companies pour less resources into making copies, instead of pouring them into making slightly different and probably inferior stuff. That means more resources left for investment on
really original stuff. Let prices be lowered faster by scale and efficiency gains by eliminating managed artificial scarcity.
And you will answer, predictably, that under these conditions the original company would not have invented the wheel in the first place, because the investment would not have been recouped.
But why was the investment high in the first place? Was the company doing fundamental research from scratch? How many actually do that? No, states do that. The high cost of research is, ironically, more and more tied, these days, to... patents! Patents held by others, and the need to acquire them or get around them. Fear of litigation. And its costs when it happens. Development can be incremental, and pay off easily, even with competitors copying what you do. Because... you will also be copying their developments.
There are two kinds of innovation: the radical one, new fields being opened, and the incremental one.
Those doing incremental development would not be harmed in the least bit by eradicating patents. The rate of development would probably increase as barriers to experimenting (costs of accessory "IP" and fear of litigation) were removed and incremental developments became the distinguishing factor among competing companies (they cannot be replicated by competitors overnight). The time window would be small, but it would be worth fighting for.
And those doing radical innovation would always have a considerable head start over any competition, because of what we call "business secrets". That doesn't mean they won't go down due to poor decisions, but it means that they have a confortable window of time to recouup investments. Most real innovators either become millionaires or fail because of lack of business skills. Not because of lack of "IP protection".
In fact in every new area ever opened there was no "IP protection" to start with: software was more freely copied in the past and not patentable, genes were not patentable, chemistry in the late 19th/early 20th century quickly developed without patents, etc. Patents came in, in each of those cases, as established companies lobbied to lock out competitors from their market after having grown rich enough to buy the political influence necessary.
