Not like physical copies may get stolen too. Thru years on gaming chats and forums (ok, reddit at time), I saw lots of stories when someone lost their libraries, but don't think even a single one of bad Steam experience, while many did praise Steam support. And no, not on Steam or even PC related gaming subreddits, but general ones. Many do not care, but Steam actually do.

Getting out of the internet coz provider things... in modern world, living without internet may be tricky anyway, not only for sake of games, but even finding cheaper groceries and promos between 3 local stores.

uBlock and Badger - more like must have base. And some I (still) dont care for cookie extension on top of that, Some pages also have extra monkey scripts. uBlock ofc with some custom lists, guess I had different to Your linked one, but added - thx!
