None of which has anything specifically to do with marriage. You can make a will and leave your stuff to your spouse, or somebody else, or your cat, or whatever. The government's only role is to register the documentation, adjudicate disputes (Is it genuine? What does this clause mean exactly?), and enforce the results.
it is all part and parcel of marriage benefits society not the individual.
the homo-con is any “love” is marriagable.
There is no love test in marriage.
There is only the primary function of marriage offspring.
Society rewards the institution not the individual.
Your argument is a pathetic “no its not” which is contradicted by a few millenia of practical experience.
We have no need for the empty future you advocate.
