This is ridiculous. 99.9% of households do not need more than 50Mbps internet. 99.999999999999% of households do not need more than 150Mbps internet....

That joke never gets old. Even if you have 4 people watching 4K netflix at the same time, thats 100Mbps (25 each required). Then you have 2 people with a PS5 playing games. 5Mbps will do lots. That leaves 40MB of headroom on a 150 Mbps connection, and that assumes you have 6 people doing all those things in the house all at the same time.....
doesn't happen.... almost ever.
I hear this complaint enough that I believe the bottlenecks they're hitting are real. You didn't allow for video conferencing, BTW. And just having a web browser open on a computer or phone is going to bring in streams of self-playing videos.
I think a lot of people are actually hitting wifi bottlenecks, well before they max their broadband speed. We know wifi doesn't scale as well with the number of users as switched ethernet, particularly if you're not using MU-MIMO.
Also, when you're doing something latency-sensitive, like gaming, you don't just want your little slice of the pie, but you actually want a good deal of headroom. Because, the fuller the pipe gets, the more likely it is that your packets get queued behind others. That adds latency and increases the chance of packet loss.
Finally, I think an underappreciated piece of the puzzle has to do with what's happening upstream. We can reasonably presume that if Google is provisioning 8 Gbps to every house, then at least
some of those users are going to be able to verify that full 8 Gbps, when they test it. That means the upstream "central office" and metro switches should have greater bandwidth, as well. And
that's probably the key.

Don't forget about updates. These only need to be large enough to momentarily tax the connectivity for others to notice (i.e. packet loss, because that's how packet-switched networks manage congestion).
unless you're a mass torrent pirate, a big datacenter, a big business, a massive operation which requires heavy bandwidth, there is absolutely no need for almost ANY household (excluding probably 1 in 10,000) to have more than 150Mbps. Consumers have been brainwashed by media corporations and ISPs in tandem to believe that they need these obscenely fast internet plans just to do basic tasks. YA DONT!!!.
In the USA, Congress killed net neutrality in 2017. Without that, you can't assume that a basic plan will have your traffic prioritized the same way as that of premium subscribers'. And if I'm right that upstream congestion is the #2 issue behind people's wifi, then priority/QoS actually matters.
I'm hardly a networking guru, but I think your understanding of networks is too simplistic.
