I think it's something totally different. I think municipalities are just competing to be the next big innovation/tech hub, now that the luster of SF has gone, and you'll see a lot of tech-virtue signaling to show that a given city is a safe-space for tech investment. Crypto just happens to be the techiest thing on people's minds, but in a few months or a year, you'll see similarly tone-def tweets about how the new Boise mayor is going to hold his first town hall meeting with the metaverse, etc.
Everyone wants to be hip, especially when hip means potential investment dollars pouring into their city.
I'm sure that's a factor too, no doubt. The two ideas aren't mutually exclusive. It doesn't change the equation. It doesn't matter if adoption comes via sincere belief or just by someone trying to ride a trend.
If you are old enough to remember the evolution of how the "Internet" went mainstream, plenty of companies that only had a vague concept of what it was and what it could do first jumped on the Internet bandwagon primarily for marketing reasons and so they could seem "hip."
