But all that requires effort. For many people, if there is an obstacle that takes away even just several minutes prior to actually playing the game, an important time window might be missed and the opportunity gone.
Also, sitting down in a dedicated space that more often than not features associations of work, an office etc. to play a game has a completely different vibe to it. You pretty much are required to switch your head space to "gaming", it becomes a thing, something serious, non-casual. Depending on your living arrangements, you're isolated from your family sitting in the living room while you're in the "office space", playing. You're not lounging on a couch since that isn't all that compatible with the input style of most games (ever found a relaxing pose operating a keyboard and mouse? For the love of god, teach me). I know PCs handle controllers just fine, but IMHO, not many games are optimized for controller usage on PC.
All that doesn't really lend itself to a lifestyle where gaming, while still being enjoyed, simply doesn't have the same goals or can even attain the same priority in life.
Let me shave off 25 minutes of my day to just relax on the couch dude, life is hard enough.
