The key sticking point is the Irish border and how to resolve that. I'm not sure it's worth going over the issue again. But the current solution, ie a "backstop" in the absence of anything else, is what the main complaint from Brexiters is. If you can explain why it is after all not necessary to have *some* solution to it, or how "No Deal" -- and the resulting necessity of a border in Ireland -- is a resolution, then, sure, you're right. But currently all major parties outside the Hard Brexit camp agree that the Backstop is necessary in the absence of any other solution, that it cannot be temporary (or else it wouldn't be any use as a "last resort"), and that No Deal doesn't circumvent this problem either.
So, yes: Hard Brexiters want a capitulation from the EU, requiring it to concede that everything I typed in the last sentence is wrong after all.
