We do not need third parties or fourth parties. We can eliminate them using evolutionary principles. We introduce a way for apps not to use third or fourth parties. This is a "mutation" that is lower cost than systems that use third or fourth parties. It uses principles of distributed systems where autonomous agents cooperate to achieve a task using apps. These principles are those advocated by Cory Doctorow
In practice what we can do is to leave all the data we need for an interaction on our own devices. This data is under our control on our devices. Where we can we choose apps that follow the principles and do not send data elsewhere. These apps will be lower cost to operate and will gradually replace those that do. (instead of sending data our systems are such that two autonomous agents agree, through an app, that they have the same values for data items).
We don't try to stop or control apps that "do the wrong thing" we provide lower cost ones that "do the right thing". People can then choose which ones to use.
For those that have been following my envesting posts I expect that we will start to keep our money on our own devices. Banks as we know them today will change from places that create money as debt to apps that coordinate the movement of money between autonomous agents.
If you think this is a worthwhile objective please go to
https://pozible.com/project/rent-and-buy-1 and buy a Reward. What I am trying to do is to persuade lenders to write apps so that people buy houses over time without the need to create any money to do it. People use existing money with envesting loans. Not use newly printed money from Bank Loans.
