This is magical thinking, because it’s using the legal system to solve a technical and social problem. It’s probably possible to create standards that don’t leak PII and other forms of metadata that are unique. That is probably the only solution going forward to reduce possible interdiction by extralegal third parties. However, Comcast can only be enjoined from doing this legally, and will likely not do anything that isn’t implemented by standards bodies, such as WiFi standards. The fact that these capabilities are available to Comcast corporate is because OEMs that make set top cable receivers and combination cable modem WiFi routers provide these capabilities. I’m not sure if these features are standard or require a special order. Once Comcast has the data, it is available to law enforcement via the Third Party Doctrine, which isn’t going away anytime soon.
These companies are so big now, and more importantly their lobbyists are, that it is unlikely any regulations would ever come that would limit their abilities to make money off of your PII.

Is that not literally the entire purpose of the legal system?

I imagine beamforming techniques are only going to become more commonplace over time.

Unless they were legally obligated to purge it from their servers after a few weeks. Or if they employed E2EE so as not to have access to the data in the first place.
You seem to think that it would be impossible to instruct Comcast to implement on/off for the feature? That's the sort of thing that the legal system is for.
