I'm sorry if the Constitution is not as convenient as you would like, but it is worth it. You, me and everyone here are slowly trading freedom for convenience and one day we will all be slaves because of it.
“Or we could act like free adults and ask why we need permission from the government to get married?”
Damned straight, it should be between church & family.
>> If you move to Texas, and they don’t recognize your license, you could, get a Texas license, do nothing or not move to Texas. <<
“Do nothing” can’t be one of your options, since it would allow people to invalidate their marriage simply by moving. The reason why the state has an interest in marriage is because a marriage contract is a business arrangement, even if it is also so much more than that.
Having states disagree as to whether to recognize the validity of a contract is lethal to whatever matter is being contracted, which is precisely why the commerce clause exists: so that on issues where there is a critical lack of standards among the states, Congress can establish uniform laws.
The founding fathers never imagined was that the definition of marriage would become so perverted that Congress would need to establish a consistent definition of marriage among the states, so there’s no clause to enumerate that Congress may protect marriage contracts across state lines in the way that the commerce clause enumerates that Congress may protect business transactions across state lines. (The commerce clause, infamous for permitting the federal government to dominate or strangle business, was actually intended to protect commerce from inconsistent state action.)
