An imaginary scenario:
Warren Buffet may want to sell to George Soros a half interest in one of his company.
Because he would make a substantial profit on the sale of his company by selling it to George, he would have to pay a significant tax bill.
However, being a savvy business man, he will quickly figure out that his best bet will be to marry George for a limited period, to transfer half of his assets in the given company in the privacy of his own home and then to divorce George in a precontracted, amicable manner.
Clearly, based on the Texas "privacy" decision, polygamy will be legal by the end of the year and so will business transactions conducted between family members in their own home.
Once it becomes evident that the new "marriage laws" can be easily manipulated, the government will be forced to revoke all "marriage benefits" including asset transfer rules, marital tax benefits and commmunity property rules that were put in place to protect the children and the spouses.
When marital rights are revoked because of abuse, it will become virtually impossible to have a stay-at-home parent, because the non-working spouse will have no assets and no retirement provisions that are not subject to massive taxation.
The family unit will be destroyed in all but a very small percentage of religious homes.
