Why do people forget that in 2011 you could have bought a used copy for $19 and even less with a trade on of a game you already finished? The digital market is not the same.
There needs to always be multiple game stores to keep prices in check. Steam can not be the only option or prices will skyrocket. See game console stores for reference. I use Playnite to seamlessly bridge my game libraries from Steam, GOG, Epic, Amazon Prime, itch.io etc. This is the way.
