This logic doesn't apply to single player games. I tried playing a racing game on Stadia and it just didn't feel good.

On the other hand, I tried the Resident Evil Village demo first on Stadia, and eventually even bought a full copy for PC. But that game is slow anyway.

Indeed. Count me as one person who was negative on stadia at the start (worked for a company where the CEO wanted to try to copy the idea, I said don't bother)
