I have expressed my top most reason for leaving that reason on it's own is enough reason to leave in my opinion.
Don't worry too much though I still don't think of remainers as bad people.

Assuming you mean the end of freedom of movement. However it is not at all certain that implementation of a points based immigration system will lead to a drop in immigration levels - as immigration is required to keep the economy and public services running.
For decades politicians have been happy to blame free movement and/or "illegal" immigration for many issues that they have not bothered to manage properly.
The points based system may turn out to be better than the current earnings based system for managing non-EU migration - but, even here, does not guarantee any drop in figures.
From the other side - it will almost certainly reduce the opportunities and freedoms of UK citizens to work or live in Europe.
Overall, from the UK perspective, I'd count it as a loss of freedom in exchange for uncertain gains.
