claiming [...] you can play any steam game without Steam is flat out wrong.
You should go inform yourself, many games on steam can be played without steam. I've even shared my copy of a game with a bunch of friends and we all played together in LAN, with a single copy of a Steam game, and only I had steam installed since this was at work.
Steam does not enforce games to require steam, it is not a requirement, it's available for those who want to use it.
Writing is hard, huh? According to the dictionary Any means "some, or even the smallest amount or number of", therefore "you can play any steam game without steam" means "you can play even the smallest amount or number of steam games on steam", or in other words "you can play one steam game without steam". And like I said you can in fact play more than one steam games without steam, therefore you're wrong.
