It can be a drawback for additional wives though. Additional wives have absolutely no legal claim to anything they've contributed to the household of a legally married couple or any financial security if anything ever happens to the husband, the legal wife has control of the household assets and finances. It's something many people on here don't like to acknowledge for some reason lol
The issue of contribution varies from state to state. The issue of inheritance and assets can be handled with a trust in any state.
No question about handling health care issues for Steve or the kids.
The issue of medical decisions won't even come up in most cases. If you say you're the wife/mother they'll listen. If it becomes an issue then you can whip out the medical power of attorney and lawyer business card.
But if something becomes an issue of medical decisions with kids all this is moot. The state will happily take control of your children at the drop of a hat in order to maximally harm them and extract as much money out of you / the government as possible.
Your daily reminder that doctors are evil.
