Also, it's legal to make a backup copy of something you own for personal use. And yet we can't make backup copies of games even for personal use. I guess we don't own them.

Right now you buy games and only you can play it. Which is different with any other form of physical good. I buy a car I can let someone drive it for a day. Why shouldn't this apply to digital goods as well?

Yeah absolutely. Which is something I am completely agreeing of. But the thing is that doesn't give us the right to steal it or make ourselves think it is not stealing. What I am doing is not buying such companies' products + pirating if I really need it. But I don't try to make it seem like how it is not (e.g. as it is not stealing).

That's how piracy started, because we couldn't share our goods with friends anymore. Digital companies decided it's loss for them.

I am pretty sure when Napster was a thing music CDs were still a thing as they are now too.

I don't know about you guys, but I share my digital games all the time. Steam and Switch have pretty decent share setups.
