Maybe, consider that it's not about you but about everyone else. I don't have a water cooled led blinking monstrosity hiding under my desk pretending it's a industrial vacuum cleaner. So, any game I play, I'm dealing with lousy framerates, and endless tweaking, etc. I never really invested in owning consoles. And I stopped buying games years ago. But I'd probably play Red Redemption and similar games out of curiosity if only I had something to play it on at a reasonable price.
In other words, Stadia potentially solves a problem for casual gamers like me already used to subscribing to content that might like to try out a few high end games but are not willing to spend gazillions on the latest gear.
Of course Google's execution here is worth criticizing. It looks like they got a giant meh from the gaming industry and are showing off another empty room problem. They need a catalogue and a marketing story around it. Neither is something Google has ever done well. They just don't do the content game very well. Youtube premium/red/or whatever it is called is pretty much dead in the water for the same reason. It's the same failed strategy: build it and they will come.
