There's a HUGE difference between video and streaming a game. In first case no one cares about latency and no one really looking into minor details in the picture so minor compression artefacts isn't a big deal. Even if you have rather crappy connection you can get away with video precaching for about 30-40 seconds then streaming ahead while you'll be at the middle of that cached chunk.

Now for games - your client sends data to the server, server processes, replies and sends video data. Which adds insane amount of delay. Now imagine it's a versus game - everything doubles. And that's in perfect condition - everyone got 1Gbps internet and lives close to the server. We all know how laggy MMORPGs usually are and those don't stream video and doesn't require insane amounts of bandwidth. It's just a delay between client and server plus server getting overloaded quite often. In case of streaming theres also well... delay added by video streaming. I laughed hard when SNK released latest Samurai Shodown on Stadia before releasing it on actual PC, how will you even play it with input lag about 300ms? It's a game where every frame matters and delay more than 10 frames is pretty much unplayable, ideally it should be under 5. Now then there's quality problem. You can't expect cloud gaming service to stream at least Blu-ray
and many games have a LOT of tiny text. Not to mention that not many people will be willing to play for "1080p-4k" quality that actually looks more like 720p.
I tried Steam home streaming thing and other similar things. They looked rather meh even between two desktops connected with 10Gbps LAN.
That's why most cloud gaming services that don't offer access to 1000+ games for a small monthly fee failed miserably.
Who will want to pay a LOT for inferior experience.

Like stillborn Stadia where Google had the audacity to ask full price for games you don't own at all and even with subscription fee on top of that (later they dropped it but still... talk about greed bigger than universe).

Game streaming won't be even close to real hardware gaming in the next 60+ years. Because to eliminate delay we'll need some kind of FTL transmission methods. We don't even know how to do that in theory. Hell, even warp drives are possible in the realm of hard science theories but there's nothing much about possibility of communications faster than radio/optical.
And just to get picture quality on par with what video card outputs to your display when streaming video we'll need trunks that more thick than what providers use for the whole city with population of 1.5M people. Something along the lines of 1Tbit/s at home. It took more than 30 years to get from 10Mbit/s to 1-10Gbit/s even for just LANs. So it will take at very least 15-20 years for home internet to get 100 times faster.
