Sounds great, bugger off on boat and let the world fall to pieces while you’re sipping a cold one at anchor somewhere.
Unfortunately the reality will be a visit from a large angry scaffolders on their jet skis, you’ll be getting chucked overboard, they’ll take your stuff and giggle while you drown.
Sorry to break it to you, the sort of people that should be in prison will do well during the breakdown of society and anyone with an ounce of kindness and decency won’t last 5 minutes!
