I'll put in my two cents on economics and foriegn policy.
For economics: If we're talking about a micronation, then something resembling a barter economy would be fine. Otherwise, I'd advocate for a state-owned fiat bank (intrestless, ofc). In anything involving money, we'll also need to have a tax policy, which I believe should be as simple as possible. Either a scaling tax bracket (i.e. +2% for each 1000 Smackerolios earned in a given period) with no
exceptions (as all exceptions can potentially be abused), or
a flat sales tax (this would need to be higher, 25~50% depending on how lean the government is) that applies to every good sold, with all other forms of taxation abolished.
For foreign policy: As isolationist as possible. The ideal would be for us to achieve autarky, for maximum isolationist potential.
Honest question: How would there be politics and a draft in an anarchy?
