For reference, I'm not "proposing" 100 MB blocks right now. I was
simply suggesting that if Bitcoin is to *ultimately* achieve the goal of
being a globally useful payment rails, 7tps is embarrassingly small.
Even with off-chain transactions. It should be a no-brainer that block
size has to go up.
My goal was to bring some long-term perspective into the discussion. I
don't know if 100 MB blocks will *actually* be necessary for Bitcoin in
20 years, but it's feasible that it will be. It's an open, global
payments system. Therefore, we shouldn't be arguing about whether 1 MB
blocks is sufficient--it's very clearly not. And admitting this as a
valid point is also an admission that not everyone in the world will be
able to run a full node in 20 years.
I don't think there's a solution that can accommodate all future
scenarios, nor that we can even find a solution right now that avoids
more hard forks in the future. But the goal of "everyone should be
able to download and verify the world's global transactions on a
smartphone" is a non-starter and should not drive decisions.
