All you're saying is that to be successful the userbase just needs to grow by an order of magnitude, which is exactly what one would predict if the demand for transactions is exceeding what 1 MB blocks can provide.
He is also saying his fork will continue to exist regardless. That's fine, he can use his inconsequential fork as long as he has another node to connect to (even if it is his own). He can also use Open Transactions he is selling as a solution all he likes too.
I suspect most of us will not support a fork that doesn't scale to its potential. Zealotry is not a good reason to keep a crude network management rule that has served its purpose and was meant to be improved. Much of the protocol was meant to be upgraded and replaced as needed. The 1MB limit increase will likely be the second improvement of many. The first as I understand it is block V2, which is still phasing in. Others like the hashing and key algorithms appear to be fine for the foreseeable future and probably all our lifetimes, but they will change eventually if bitcoin doesn't die. The txn limit is actually much lower than 7 tps if bitcoin ever sees significant usage of any of it's coolest features, like smart contracts.
