It costs real money to buy back tokens from the market and to burn them on the blockchain because they are provably scarce. Because new tokens cannot be created, burning them on the blockchain permanently reduces the remaining circulating supply of tokens so the value of remaining tokens goes up (supply versus demand).
Someone could potentially funnel money out from the stream of profits but anyone could independently check expected earnings (looking at the assets in the portfolio) against the on-chain buyback amount. At least, it significantly limits how much money can be funnelled out.
On the other hand, with a regular company, the directors can make up any numbers on the books and funnel out all of the profits and could keep this going for years undetected. That is far worse.
Altogether, it's not 100% trustless but it's orders of magnitude more transparent than a share-based system. As a small business with directors located in different parts of the world (some of which only met over video chat), this model was essential for us to get over the trust hurdle. Now that we can see tokens being bought and burned, it is building trust within the community. Many community members have already sold some tokens back and seen them burned. Some small investors already made a profit over their initial investment and still have half of their tokens left.
That said, it's not going to be ideal until we we multiple real estate companies (run by different people) hooked into the LSH blockchain. The more companies there are, the less trust there is.
