Thanks for looking so deeply into it. To generalise in answering these questions, it's mostly because we are in beta at the moment. We don't know what the numbers will be like, that will be to do with adoption. The more that whales support our efforts (and it's in their interests to do so), the more we will be able to support the promoters. Everything will be transparent, and there will be multi-proof-of-brain built in to the guild system.

In terms of hosting outside of the EU, this is because there is a particularly pernicious bit of legislation coming into force in the next few months. Of course, the powers that be always want to regulate everything, but we are a voluntaryist set. We want the community to run itself, not have to fuck about dealing with compliance with draconian legislation. If the community as a whole decides it wants the webserver hosting in the EU, then that's what we will do. But until we have community involvement (Which is the point of launching now, so we can get it) we have to do what we think is best.
The microloans...I agree, and we are talking about micro.....and we are talking about interest free, repaid by the promoters getting their promotional activities upvoted by the community (that we are supporting). The lenders are all fully aware of the risk, and they are private steemians. It's interest free for the life of the loan. People who fuck off with the loan (a) won't get another one and (b) will get called out to the community, which is probably the worst thing that can happen. Everything will be on the blockchain and transparent, so everyone will be able to verify everything. Essentially it's P2P lending purely for promotional activities, and small amounts.
I hope that clarifies some of the points for you, and once again, thanks so much for taking the time to read so thoroughly.
