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.

The situation has changed quite a lot with digitalization. When copyright was developed, giving up the right to copy something had low cost - you needed to have a printing press. Now you can’t even read a book without making multiple copies, so the cost of giving up copy right is a lot higher. The benefits to society of securing an exclusive right to control copies is possibly unchanged, or perhaps less as the writings can no longer be retelling of common stories (e.g. Disney movies from Grimm brothers; Shakespeare mixing popular stories into brilliant plays). I suspect making the timelines of copy right protection be shorter (as culture speeds up) rather than longer as we have done, due to the weirdly long lifetime of corporations, would fix most of the issues. Invention would be rewarded without the creation of IP monopolies and the restriction of mixing existing stuff as a creative method, and the loss of the right to copy stuff you have paid for all lessened.

If that's the problem, we also need to ban society - cause one can be more prosperous than other, and it disadvantages those born into the latter.

So is citizenship. Should we do away with that as well?

I suppose because we're wired this way. Can't think of any group or society that didn't have some notion of private property that wasn't just a huge (and brief) humanitarian tragedy.

My life, yes, but my genetic lifeline exists up to and including eternity if luck and good decision making are on the side of my generations of offspring.

Let's consider the most basic form of ownership: that over one's body. By your logic, my life is a spec on the eternal timeline, so why make it a crime to harm or murder my physically?

The argument is that taxes were already paid when the relevant work was performed. Transfers of ownership that don't involve work (ie economic activity) shouldn't be subject to government interference.

The obvious issue is that if you don't tax gifts it becomes far too easy for people to dodge taxes (or at least much more convoluted to enforce payment).

Inheritance is much more complicated and controversial. There's an argument to be made that it results in social ills if left unchecked, an argument that estate taxes fail rather spectacularly to address those ills, and an argument that the ills tend to be self righting given how easy it is to lose money. And probably several others.
