No.
Leaving the EU is a separate thing from the trading relationship we will have with them afterwards.
For example, if you left a job, your employment status afterwards would be a separate thing from you leaving that job.
The reason that deal/no deal has been attached to leaving the EU, is to try and stop us leaving the EU.
"We can't leave without deal" = "we can't leave the EU".
UKIP had the best answer to this, which of course is why they were attacked relentlessly: leave the EU, THEN negotiate with them to see if they want free trade with us.
This isn't like leaving a job though - we will still maintain a relationship with the EU after leaving, leaving will also upset many of our existing agreements with other countries that aren't themselves part of the EU due to us working, upto the point of leaving, within the framework of the EU.
Your thinking frankly is dead wrong.
