Well tell us then FFS! Don’t just keep saying that Brexit is costing everybody more. Assuming you come under the heading of 'everybody', tell us EXACTLY what it is costing you.
Lots of stuff, roaming charges, prices in general (food and non-food) post to EU (delayed and more expensive), firms not delivering to EU, restrictions on customs, queues at border crossings, lack of available merchandise, transfer registration of vehicles (including trailers and caravans), friends and relatives visiting EU family/friends for long stays.
That's just a couple of issues off the top of my head.
And if you done't believe me, try lots of ordering online, and using an EU address. Try a long stay to friends or family in EU. See how the visa process is a pain, the stamps in your passport filling up your passport, not being able to be employed in EU, the roaming charges, etc.
I know the same applies the other way as well. You can get a lot of stuff in UK from EU, but a) it's delayed, b) it's more expensive, and c) there may be VAT, etc payable.
Then talk to an EU person who wants to relocate to UK, and to work. (the same issues as vice-versa)
None of these issues might bother you, but there's lots of people that are affected, and for what? Take back control (to allow more pollution), sovereignty (what does that even mean)?
