The most efficient market is decentralised and runs on a blockchain

methodology of introducing a lot of noise and irrelevant numbers to hide information, would be good at politics

more practical methodology: The cash-only person who lives in the forest (finally got treated for his paranoia) wants to convert his money to electric, and maybe wants to trade that money.

What is the costs along the way of (assuming he has an ID) getting any financial accounts required in the way of acquiring the desired digital money or asset, And then what is involved in a second transaction, once already involved in the system

e.g., for Spaceship in Australia, step 1 would be to open a debit account, step 2 would be to deposit that cash into that account, step 3 would be to send that money to Spaceship

The account, deposit, etc, have no fee / only a monthly fee, spaceship has its own fee, add those together, thats the overhead of the initial transaction
