Here's an interesting idea:
What if small businesses issued e-cash in-store credit? It could be in terms of "hours of labor" or a specific good or service. This would make it exchangeable to other users, while technically not inflating the currency. This could also allow a small network of businesses and individuals* to trade their goods and services** without the need for a more widely accepted currency. It's putting trust in neighbors, again. Heck! You could issue stocks in e-cash!
* the first thought I had was farmers' markets and very small businesses
** like the bread credits referenced in nostr:npub1a2cww4kn9wqte4ry70vyfwqyqvpswksna27rtxd8vty6c74era8sdcw83a's recent video
