It exactly how you say, with a lot of people not exactly working in UK leaving, people who made money abroad. I know plenty who do. I can see your point here.
The problem here is the way they are implementing it, right now you would still pay taxes on brining money to UK, also all of those people who happily pay certain amounts or smaller percentages on % of foreign income to live in the UK. However 45% of income made completely outside of the country is a robber and people are leaving to UAE, Italy, Switzerland. Italy is charging 200k flat now a yearn UK they would pay more.
Also office of companies are getting relocated, they stop spending money here, they would pay higher to stay in UK.
So if you say you were to get 300-500k per year from those people and now you get 0, and thousands of people leaving it goes to billions in budget loss
