UK also isn't in dire straits compared to a lot of other countries out there, and therefore they haven't got desperate enough to try new alternatives. UK was somewhat late in bringing in taxation for Bitcoin, but they've since made the most of it.
They will just implement what US are doing. They will adopt Bitcoin and crypto to get more tax as the government needed more funds like every country struggles today.
Nothing to respond to it really as if a regular gambler can do something about it. Anyone from UK who gambles using crypto will just comply if he wants to continue what he is doing.
