Earlier quoted context omitted.
If we could kill patents altogether that would be a much nicer step. Patents are an invention from another Era and make absolutely no sense nowadays, and we see them constantly abused to make our lives worse in the end.
No it wouldn't. Talented people would have little incentive to create something new.
What patents were set up to prevent, IIRC, was trade secrets - they were a way to bribe creators to publish their ideas rather than sit on them.
IMO, they were a sledgehammer to swat a fly. Trade secrets would be reinvented. Locking an idea out of the commons for a whole patent term (and longer if they can attach new patents off the side) is a worse outcome.
