One thought I had: keep your assets in bitcoin, and you don't have to worry about passing on your wealth to your spouse should you die. No issues with estate or inheritance taxes (gay couples have to pay taxes on
things they own if their spouse dies, while married couples just treat it as inheritance), and no issues with parents that didn't approve of their kid being gay coming in and taking all your stuff, because they are family and you legally are not.

Change from "miner" to "phone" and change the long string of text to a QR code, and DO IT!
