Without doubt, ownership of land is crucial to any citadel concept, in spite of how flimsy property rights may have proven to be in certain places

Also I like the idea of making the screening more difficult. An investment group is a good start 

nostr:npub1jmy8weweqzckna0amz7pn0uhhkxx693l7st23829ewmu43yvjsesfp6xcq was very insightful talking about this in relation to a property in Australia, in particular to the opportunity cost of land vs more BTC

So a group willing to forgo BTC to buy land lowers the risk for each investor in a sense 

Plus yes, the idea of trading directly between specialised operations makes lots of sense 

Love to hear more about how you get on

👏
