This is an important observation. Your neighbour trusts you because of the relationship you have with them, your membership in the same group (home ownership in a neighborhood), proximity and availability (they know where you live and can contact you easily if they want the weedwhacker back), and you already have collateral in play (ownership of your home and reputation in the community). The key to building trust online is to recreate some of these aspects. You should have an identity in the community that you belong to and you should own assets under that identity so you can’t easily abandon it and start somewhere else with your ill gotten gains. Communication amongst members of the community should be easy and common. There should even be shared ownership of community assets and the community should provide services to its members. I imagine this looking something like a discord server combined with some of the hosting features of FB like image sharing, posts, groups, etc. You’d also need a built in token that could be used within the community but also exchanged on a broader network of federated communities.
