Xanto: There is a chance I might lose access to all my Steam games at some point in the future, I honestly don't feel that much safer with having DRM free games either. In 10 - 20 years GOG may not be around, and without them constantly updating there games (which is unlikely when they get to the point of having 1000's of games anyway) newer technology could easily make all our DRM free games useless anyway and sure we could keep old tech around to play these games but that will only get us so far when that breaks and goes away as everything does.
That argument doesn't work at all. The DRM is an _extra_ potential impediment blocking you from playing the game that you bought earlier, not an optional. So yeah, without DRM you might not be able to play the game on your future PC and OS, if you don't have your old hardware around,
or an emulator. But with DRM it is even worse, you might not be able to play your purchased game even if the game otherwise would run fine on your future PC
or emulator, or even if you had the old hardware around.
Your argument is the same as saying that it makes no sense to use a safety belt while driving because you would die anyway if your car got crushed between two high speed trucks, or if you drove off off a high cliff. Yeah, but how about all those other potential scenarios where the safety belt would help you immensely?
Or, taking a travel insurance doesn't make sense because someone might kill you while you are abroad. Ok, but what if you wouldn't get killed abroad, would it still make sense to take an insurance?
Copy protection or DRM schemes are the main reason old games from dead systems can't be run on e.g. emulators, while the DRM-free versions run fine. Try running your original NES Super Mario Bros cartridge or a copy protected Amiga 500 floppy game disk on a Nintendo or Amiga emulator running on your modern PC: nope, can't be done.
Next, try the same with the DRM-free/copy protection free version of the same game (basically meaning a ripped/pirated version, where someone has removed the DRM/copy protection/media dependency), and suddenly there is no problem whatsoever running it.
