Stupid?
OK, lets go through it....
a) Pound down, imports down, exports up, jobs up.
b) Jobs up, benefits down, tax (or deficit) down
c) Payments to EU eradicated, tax or deficit down
d) Freedom to do what we like, more freedom to create jobs, support critical industry etc. more jobs.
e) No rules used by government to justify buying Spanish tanks, more British tanks, more British jobs, more British investment, more British exports, less tax
f) The list of good goes on for many pages.
And yeah, I am sure the EU will continue to spout bull about 'no access to the single market without our rules" but bull is exactly what it is. If we can't sell there we stop them selling here... no spares for a bmw, no french wine, no italian cheese etc etc etc, they export more here than we do there, they will hurt most. We then offer country to country trade deals, I don't care what the rules are they club wont stick together... and even if it does there are massive markets outside the EU for us to sell to. And if we can't buy bmw spares we will make them, if we cant buy french wine we will make it, if we cant buy italian cheese we will make more of our own... more jobs, less tax, no losing for us here.
Now, put all that benefit against the fact you might buy a PC every couple of years and it might cost you a bit more than it did... I think the balance is clear. (Besides with the lower tax you can afford 3 or 4 new PCs anyway).
Have fun :)
