For data that is “mine”? Yeah.
But the average steam library (from just asking chatgpt because i am lazy) is 30-100 games for a “normal” user and 200-300 games for an “enthusiast”. Assuming 10 GB per game on average (which is woefully small these days) and you are expecting people to spend 1-3 TB of storage on just their game installers alone. AND that is assuming none of those installers get updates and people need to figure out which ones (most of us who lived through The French Monk incident can attest to that).
So what happens is “oh, someone else will back it up” and so forth. And it means EVERYONE is grabbing torrents for Spec Ops The Line and not just the people who didn’t think to buy a copy while they could.
