Off chain transactions are not a solution.

For one thing, off-chain transactions means giving up every advantage of Bitcoin - you're now stuck working through some kind gatekeeper service which has the ability to exercise prior restraint (censorship) and probably chargebacks and funds confiscation.

It's especially pernicious when there are about 7 billion people in the world who haven't got a chance to buy Bitcoins yet and they are the ones who most desperately need censorship-resistant money. The proponents of the small static blocksize are effectively locking them out of the benefits of Bitcoin forever.

Secondly, we need massive amounts of transactions on the blockchain in order to generate massive transaction fee revenue in order to pay for the hashing power we need to secure Bitcoin against attackers with nation state-level resources.

Bitcoin won't stay free with small blocks. There's no route to that outcome without sucking it up and making large blocks work.
