The lack of liquidity happens because you are not using fungible money, so you are asking everyone to barter, but instead of using cows, wheat or some other commodity, people would be trading based on the expected value of each personal bond. Given that these bonds do not pay any interest, there will be very few people interested in accepting them for payment.

Re: profiting from the Blockchain, you are going at this backwards. You don't need to make it profitable by the tech. What we want is to have a global payment network that can make transactions cheaper than (and equally faster/secure as) Visa. If that were possible to do without blockchains, the market would pay handsomely.
