UK Banks Banning Users From Buying Crypto. Claims "It Is Not Safe"

Some of the biggest banks in the UK now halt transactions and decline cards whenever their users make attempt to buy some crypto particularly via Coinbase and more banks are expected to follow this trend. Their reason for this is that they think they're in the best position to direct their users who have worked really hard to make the money they keep with the banks, on what to spend it on and what not to spend it on which is totally absurd.

Some notable banks like Nationwide for example on declining cards trying to purchase crypto claims "the transaction isn't safe" and I wonder why they don't keep the same energy with betting platforms and casinos.

Firstly, what is with banks and crypto? Why are they so scared of something that "doesnt have value"? It does seems like they are beginning to understand how crypto is indeed here to revolutionise the financial system for good, but they keep taking actions to slow it down. For example, banks here freeze accounts linked to either buying or selling of cryptocurrencies but still, that didnt work, thanks to P2P.

One would expect the UK to allow the citizens spend their money how they like especially when the money isn't spent in anything that endangers their lives or the lives of others. This move of restricting users to not buy crypto via bank accounts only makes it more glaring that most banks and government don't just crypto as a threat, but they also see freedom and liberty as a threat and it is really just a matter of time before their plan to keep the citizens in chains comes crashing.
