With the current 1mb limit, bitcoin won't even work as a store of value as investors will have to waits days to get their transactions confirmed. That is slower than even the SWIFT system.
The block limit on the 1 mb chain will have to be raised even for LN transactions, because on-chain transactions will be required for opening a LN channel and closing it. So ether way, the block size has to be raised.
BTC is going to need to continue to evolve. Consensus on larger blocks looks to be essential
