It has to do with Tyranny of the Majority.  It's not acceptable for the majority to infringe on the rights of the minority or an individual.  If it were, we could hold referendums on all kinds of ridiculous things.  As soon as it appears someone's rights have been infringed upon, whether it is by a tyrannical monarch or a majority vote, it becomes a constitutional issue.  Hence a constitutional lawyer.

For instance, we could hold a referendum to:

1) Take your house away and give you nothing in return.
2) Throw you in prison.
3) Deport your entire family to North Korea, except for your dog.
4) Let Justin Trudeau adopt your dog and rename him Justin Jr.

If we achieved a majority, then we could just point at the referendum and strip you of all freedom.

As silly as these things are, the constitution is what protects a tyrannical majority from infringing on the rights of the minority.

I am not saying this is anything more than NIMBY, but if it is, then we have a problem.  Make sense?
