If I come up with an invention I don't have the capability/finances to bring it to market. Without patents, I have no incentive to show it to possible investors/manufacturers because they can just steal it and keep all the profits. So my idea that could have helped society dies with me. So it costs society nothing to give me protection, but society get's nothing without the protection versus efficiency, safer working conditions, better health, whatever benefit from my invention.

Without copyright it was hard to assemble high quality educational books/manuals, because they take a lot of effort with relatively little reward/return. In fact the first 'modern' copyright act in 1701ish was titled something about improving education.

Without copyright it is not worth it for authors to spend nights/weekends flushing out plot ideas for complete sharable works, so you end up with less/lower quality literature as no one can be a professional author. Which has better quality on average, published books or self published? Self published tend to be the 'passion projects' you would still have without copyright, published books tend to be what get's created when authors are compensated for their efforts. Society can't lose from copyright because without it the works would never have existed. If I say 'I'll bake a cake if you will buy a piece' and I bake a cake and sell a piece, society didn't 'lose'. If I don't bake a cake because no one would buy a piece than society was a little sadder, a little plainer that day. There is only upside, there is no downside. Anyone that would release if copyright didn't exist is still free to waive their copyright protection. So having it is the best of both worlds, those that want to release just to release can, and those that want to try and create something that can be sold can.

Without copyright there are no big budget movies, only passion projects because no one is injecting millions when the work will just be copied no sold/screened/rented.

Without copyright the world has less joy, less discussion, less contemplation, less entertainment, less education. Without patents the world has less productivity, less safety, worse health, less food, worse/much less clothing/housing, less free time. The systems in their current forms have been abused and are unfit for the original purpose but when kept to the original purpose with reasonable protection periods they are a HUGE net plus for society.
