Oh, I'm not commenting on the overall effect. From what I understand, international trade absolutely did get more complicated.

On the other hand, though, it gives the UK a bit more freedom to set its own laws and make its own agreements.

VAT laws that are actually designed to collect VAT, for example, plus we finally have a UK-AU FTA!

VAT is just as complicated as it used to be, especially if you sell into Northern Ireland. The only thing that improved is we don't have to do those bloody EU sales lists.
