Pretty uniformly, people want the benefits of bitcoin and the blockchain - near-instant transfers, globally available on any Internet-connected device, highly secure, and nearly-free value transfers.
I've spent a lot of time being bohemian and sleeping on floors, but eventually I want to have kids and I want to bring them up in a secure environment.
I like marriage. I feel very secure. It helps when you are in love with the person you are married to.
It's nice to be financially secure. Apart from that, I really don't care too much about money.
