> I obviously can go around punching people in the face on the street. What use is there to forbidding that? Perhaps that it's beneficial for society to discourage people from doing certain things?
Right. I have to agree. Still, somehow copyright feels more like punishing people for not praying on Sunday than punching people in the face. All forbidden things are definitely not equal and some, naturally, feel more deserving of being forbidden and more easy to enforce the punishment for them without invading personal freedoms and privacy. It's entirely pointless to forbid things that don't (even potentially) harm living beings (there's no human right to having a viable business model) which would require permanent invigilation (even in private) for full enforcement.
> patents (N.b. copyright is far from the only law that applies to intellectual property) were created in order to encourage people to share their ideas
Which pretty much failed spectacularly and should have been ended about 100 years ago when it ran its course. Way before such abomination as software patents spawned in somebody's mind.
> Because exactly the sort of "free for all" rights you are arguing for meant a
The world is free for all. Every industrial economy that got big, got there by disregarding intellectual property. Even US, blatantly copying industrial designs from UK. Intellectual property is kicking off the ladder.
> huge incentive to keeping everything as secret as possible
There's only so much you can keep a secret if you want to go to market with it.
And despite wonderful protections of intellectual property many companies still choose to keep as much as they can secret. Because protections can't physically work 100% and they need to be 100% for them to work at all.
Patents serve many purposes but none of their stated goals.
> Finally, can you explain what you think stealing is?
Depriving someone of possession of something by taking the possession of it yourself. For data economy it can be slightly extended to taking the copy of information that is held by someone else without their permission (hacking basically). To be fair we should make another label for this act if we want to keep the original meaning of the word steal intact.
> Why is it a crime for me to take one bike to work but not the other, if they both stand unlocked outside the building?
Because you can keep your items in public spaces. This changes dynamics of theft a little bit. It is a crime to take my item that I left in publically accessible place because after you did that I no longer have the item.
If you were to just make a perfect copy of my bike that I left in public space, that would be totally ok because I would still have my bike.
The harm in act of stealing is not taking possession but depriving someone else of their possession.
