I understand everything you've said which basically boils down to:
Let's not worry about the consequences of our actions, let's just jump off the cliff without safety net.
Let's not worry about uncertainty, let's just call it "opportunity" and everything will be fine somehow, right?
Only problem is, not even sweet shops are run like that, let alone Countries.
Let's just hope that Boris and the rest of the Brexiteer muppets (with loads of ££££££££ in their bank accounts leading the plebs-what an oxymoron!) have a slightly better plan than that. From what I have seen thus far, in fact, I don't think they do.... But hey, we got that trustworthy chap Trump supporting us now, telling us to go ahead with Brexit, deal or no deal! Hooray! I feel much better now! Yeah!
(only he won't be held accountable for whatever happens after...)
PS - To make myself clear - all this time I have been talking about a NO DEAL Brexit. If there's a deal, I got no issues.
