EU referendum, brexit and the aftermath

The problem is that the ERG and its ilk simply want to fall out of the EU with no deal and let the chips fall where they may. Hang the short- and mid-term consequences (which they won't suffer anyway), it's about long-term freedom for the UK (to turn into some Thatcherite/Randian, low-tax, deregulated, minimal public service, unfettered free market utopia).

Aside from the fact that this has horrible implications for much of the population, it's deeply undemocratic. This is not how Brexit was sold during the campaign, that was all about close ties with Europe and all-of-the-benefits-with-none-of-the-costs. How can it be in line with a democratic vote that we end up defaulting to a no-deal situation as a failure of the process that people voted to put in place?
