for the government to tie any traffic directly to an individual would require data from your service provider, which they generally don’t provide without some kind of legal reason.

fwiu this system would essentially make everything you view and do on the internet freely snoopable without any sort of legal order or reason. your traffic is always tied to your name or face, and you lose the layer of pseudo-anonymity from your ISP.

potential real-world consequence, you could be more easily sued by a production or broadcast company for piracy! right now if i torrent the right movie (without a proxy), i’ll get a letter from my ISP explaining that 20th century fox is asking them for my name and address so they can sue me. but the ISP won’t give the info without a legal order, and fox can’t sue anyone without the info.

so if this change happened, you’d have to hope your government decides to treat you more favorably than myriad other billion dollar companies and corporations. historically these are bad odds.
