Earlier quoted context omitted.
The term "intellectual property" lumps together quite disparate concepts. It's not helpful to use it. And "theft" is a poor analogy. I'd say society wouldn't change much if copyright were abolished. Probably for the better. Claiming authorship should still be protected in my opinion, see next point. Trademark law gives some nice protections to consumers, so I'd vote for that one to stay. Patent law? Ahhahaha where do…
Wouldn't programming, writing, music, and art as careers basically be gone overnight without copyright? Who is going to create a book, video game, or movie when they can't sell it? Programmers would be the best off of those I guess, but only because they would have the option to move all code server-side to stop piracy.
As a matter of fact, programming already works as if IP law didn't exist from the point of view of many programmers.I'm hired by a company to produce a product, in exchange for a salary. I don't know any IP that I might produce as a result of my work. I'm simply paid for my time. Could (as an example) novel writers be payed for the time spent writing a book rather than as a function of the sales of their books? I see not logistical reason why not. Maybe the market won't bear many writers under those conditions... But they would still exist, right?
Note: I think Trademark law is really good. And patents have issues but they are mostly good. I'm only talking about copyright here. I'm not entirely against the concept of IP, but I do think copyright law is not nearly as critical as it's made out to be. Maybe the optimal solution is weak copyright rather than no copyright, but I think it's important to understand that no copyright is not as crazy as it sounds.
