Re: being introduced in the UK
You don't vote for laws in the UK, you vote for an MP who you hope will go to parliament and vote in the way that you want, same as most other democracies.
Otherwise every single attempt to change a law would end up turning into a brexit, and nothing would ever get done.
(If you actually do care and you're not just trolling, you could go through the policy consultations and see who HMRC actually did ask about this.)
