And subsequently executing the exclusion constraint on "=~" also worked perfectly as expected. The larger issue I face with now is slightly out of my control without further hacking. I'm developing an app with Django and I wrote an extension that allows me to use the point type natively in Python. I ran into the original issue while an automatically generated query was executed in the admin section. I know this could be viewed as something pertaining to Django, but the goal I had in mind was making PostgreSQL functionality more accessible in a different software layer. I will find a workaround for the above, as I am sure I can do some application-level hacking. Thanks for your help!
