"I don't care if we ramain [sic] in the single market or customs union. But if we do we should not be accountable to the EU in any way. We should not accept EU laws..."
If we remain in the EU single market then, by definition, we'd be subject to its rules; ditto, remaining in the Customs Union.
So, therefore, you do care: according to your red lines, we should leave those institutions. I'm slightly surprised you didn't already know that this would have to be the case in your vision of Brexit.
