What legislation would be most meaningful to pass or amend in the US, at a federal level, if it was possible? Why?
Some profound difficulties with the question Daniel.
In the short to medium term, instigating some form of Universal Basic Income seems to be the most stable transition strategy to move from scarcity based thinking to abundance based thinking. And that is a really complex process, as the market economy currently performs many levels of essential distributed functions in cognition, governance, and risk management that Hayek and others started to identify. So those essential functions need to be transitioned to other systems.
In the medium term, a Federal program to develop fully automated manufacturing in a cooperative international context is essential. Fully automated manufacturing technology deployed on the moon would allows us to develop effective technology to mitigate the effects of climate change, and that technology is needed. No linear technologies can solve the problem, it is too complex. Such technology would also allow the prefabrication in space of a global transport infrastructure (high speed maglev trains in evacuated tubes) that would be capable of replacing air travel (electric air travel is not a realistic engineering possibility – batteries cannot have the energy density required).
Once they had replicated to numbers exceeding the human population, giving every person on the planet one would be the end of the current scarcity based system. Such technology is actually required if any of us want a reasonable chance of living a very long time, as biological life extension comes on stream.
And the real difficulty is that we are dealing with exceptionally complex systems.
Complex systems do not respond in predictable ways, and are not well suited to rule based management.
The most appropriate management response for complex systems is iterative – probe, sense, respond – repeat. Goodhart’s law applies (Any statistically observed regularity tends to collapse once pressure is placed upon it for control purposes.) So relying on laws is not an appropriate response to complexity.
We need to develop responsible attitudes.
Complexity delivers novelty, eternally.
That is reality.
That is not how most people think yet.
Currently most people still think that there is a single right way of being or doing anything.
That is not reality.
Reality allows for infinite diversity.
The tricky bit is that the infinity of survivable options is a small subset of the infinity of all possible options.
Our freedom needs to be constrained to the sets of actions that are survivable, but the issue is that the boundaries of that set will always contain uncertainty (for a host of reasons).
So we live in interesting times, and they look set to remain interesting for as much of eternity as we manage to survive in.
