Really interesting concept, localized cryptocurrencies. They wouldn’t need to worry about scaling so much, and the word of mouth network effect is probably effective as well.

I think for tight knit communities such as those you mentioned in this article, this would be a game changer.
For those which see a lot of tourists, might need a slightly different set up, probably will need crosschain transactions for example.
This is a great article, thank you for sharing and bringing it to my attention. :)
