I'm not convinced that 16ms or 6ms is the right budget to talk about. Sure, if you want someone to see the picture, make a decision and reflect it back in the next picture, that would be the budget. But take a comparison to telephony, the ITU says the budget for unnoticeable latency is 150ms. So I can talk to you on the phone with 150ms latency and not even notice. Now, I think gaming is probably lower than 150 because the timing of speech is fairly slow compared to twitch shooters, but I don't think it's 6ms. You might be right it's still unachievable (and I agree, the only viable solution might be to boil the ocean by sticking data centres on the end of every street and create a new guaranteed low latency protocol that takes precedence over all other TCP traffic), but I'm not as certain.
