Increasing base-layer capacity to, what, maybe 30–40 tps tops would be a sick joke at a cost that would surprise people. It would not solve any problems, and it would create many. We need technologies supporting tens of thousands of TPS or more; a doubling (or whatever) of the current blocksize is insufficient by orders of magnitude, too much and not enough all at once.
Do we though? I keep seeing people, big blockers and OG's alike, banging on this proverbial drum, year after year after year, as if it such a dire, imminent need.
But if most bitcoiners see Bitcoin as 99% SOV and and 1% or less as a transaction medium, then no, it's not. The current TPS limit will continue to serve just fine.
And Gresham's Law will continue to prove that out.
There is a reason why the acronym "HODL" is so identified with Bitcoin, but certainly not with fiat.
