And IPv6 addresses could provide just that I.D. system.

Why aren't companies like Google, Amazon, and Facebook lobbying against this? It seems they stand to lose the most is such a thing were used.

Obviously a permanent static address would have tracking value, but proxies and networking would seem to have equal obfuscation capability...
