What, if anything, can we do about banks blocking crypto payments?

Basically the title, seeing as the bank of Australia recently joined in on this it made me think about what can even be done.

I’m from the UK and a lot (I’d say a third) of banks just flat out deny deposits to many crypto exchanges/sites.

If all banks eventually join in on this does that mark the end for the average investor who won’t care to look for loopholes? Just seems like more and more banks are taking this approach and there is not much that can be done, curious to know how many banks in your country block payments and thoughts on what can even be done about this? Seems worrying

Edit: just to clarify I’ve already changed bank so I’m doing fine (for now) just a thought I had that if every bank joined in on this there aren’t many alternatives
