"If each node has to verify all transactions that is not sustainable in the long term."

It is sustainable, but only for certain amount of transactions. Even if the block size limit stays at 1MB, I'm pretty sure some group of people/organizations will keep using bitcoin for something. Those who are not happy with it will move elsewhere, but there is so much infrastructure/tools/etc for bitcoin already, that many have will hard time switching to something new.

Sorry, I am not sure Bitcoin can be a niche currency. It needs to be big enough to survive.

If most people prefer to use other crypto instead then Bitcoin may fall into a death spiral:

...lower the demand for bitcoins -> lower the price of bitcoin AND lower amount of bitcoin transactions -> less profitable the mining -> less secure the network -> lower the demand for bitcoins....
