Re: Change the law, then
The UK does profit enormously from it, just in other areas : see: City of London. It's largely successful because it's a regulatory haven of sorts with pretty flexible attitudes to many things.
From what I can see, the UK seems to also want to continue to have access to selling and processing EU financial services into the EU while not being a member.
Of any country in Europe, the UK certainly is not in a position to hold any moral high ground over Ireland on taxation or regulation.
