Some of these make me sad to read because it demonstrates what at least my society lacks and what it has but uses as gimmicks, as if marriage is a cult.

• I've seen married people forced to testify against each other all the time. The "right to remain silent" is universally thrown out the window.

• The "joint adoption rights" thing is flipped around. If someone is jailed, the rights to their children is taken from both them and their spouse.

• Imagine for a moment we even have inheritance taxes and rules against making arrangements for anything.

• The automatic recognition of the relationship by every state and nation is a misconception. That's how it's supposed to work due to the Hague convention, and in regular cases it does, but it's not enforced.

It's very interesting to me that people tend to mention tax breaks for marriage because it's just not the case except if one of the spouses does not work or makes significantly less than the other. For example, when I was married, our taxes went up by about 6k a year. It's called the marriage penalty tax. A lot of these other benefits also depended entirely on the state/job/facility and are still required to be granted via other documentation. For example, Florida is a probate state and requires a will regardless of marital status or you have to go through probate (ask me how I know). Medical decisions and adoption seem to be important benefits, but these can also happen without marriage. Survivor's benefits are interesting as well because those don't generally extend past the last owed check, but do still go through probate if you're in a probate state.

Just to be clear on the first two points, you can designate anyone as your health care proxy. Check your state for specific applicable forms. In general if no one is designated though it will default to a spouse.

Health care proxy is also different than power of attorney, which sometimes people get confused on.
