Actually the solution you desire to have 100% censorship-free transfer is the same solution that makes the TPS scale to any level.
Your mistake is thinking these are duals, whereas in fact they are the same network design. You just haven't seen that design yet.
Much will change...
...believe me your assumptions are wrong because you haven't seen what you can not see.
I'll be impressed if your solution can operate with less than 100% degradation under a situation where all global (and regional) internet infrastructure providers are highly incentivized to attack it to oblivion and do so with vigor. A related assumption is that the U.S. NSA or a like replacement 'owns the net' and their analytical abilities of traffic down to the individual packet level are very high.
Your (or A) solution does not need to perform in such an extreme environment indefinitely but it must have a realistic potential to hold out for a period of years.
These threats are not at all far fetched to my way of thinking. A solution which cannot deal with them is simply not very interesting of valuable to me. If we don't see such an environment it means that mainstream solutions continue to work more or less as they do now, and to me they work just fine. I'm interested in how to deal with a world in which they do not.
