No, it isn't scary. These are just additional options. Personally I prefer Geforce Now which lets me use my own Steam catalog versus buying specifically for a niche service, but people make their own choices.
Often the loudest fear mongering occurs by the hoarders (digital or otherwise) who think they are amassing some grand asset pile.
I buy a game, play a game, and then often never play it again ever. I'm not scared about the prospect of losing access to it years down the road.
