I've said this before and I won't be surprised if I say it again in the future. The only way to actually and fully leave the European Union is with 'No Deal'. Every little bit of a deal ties us to the European Union and it's rules. Remainers know this and this is why they insist on taking No Deal off the table. They want to take leaving the EU off the table. The stratagem is deeply dishonest but not unrecognised.
