I agree with you about building local communities first, going from globalization back to localization. Bitcoin is indeed internet money, but the issue I see is the lack of trust between buyers and sellers. 

In certain cases I noticed escrow services can take some risk out of the table ad mediate in case of any issue. Or even better, be the unwanted but needed intermediary to facilitate the sales and in some case the shipping, protecting in this case buyer's privacy too.

I think it is realistic, but it is a challenge that not everyone is up for. Building an agorist community locally might be a start, but with the onset of things like nostr and other online communities, there are people selling things for bitcoin every day, so it's possible, but again, a challenge. I know a few people who more than likely would sell or trade just about anything for bitcoin, including ride services, lawn care, grocery shopping, herbalism/tinctures/extractions, books, etc.
