Look at it the other way round.

Imagine we weren’t a member of the EU and we held a referendum om whether to join or not which resulted in a majority in favour of joining.  Would it then be right for us to join no matter what the deal was that was struck, no matter how much it cost us, no matter what laws we would be subject to, no matter what the effect on immigration etc.

I thought the above is one of the objections put forward about the referendum held in the ‘70s - we didn’t know what we were voting for.
