This is cool on a broad scale... But I'm not too sure about the policing limitations. I think people shouldn't be restricted by what defences they can put up to defend themselves by some arbitrary mechanic. Really the cost of making, maintaining, and powering them should be the limitation.
Also the way I see a system like this is also includes a regulations type system for different organisations and governments:
Organisational Authority(Controls the organisation polices)
Local Authority controls Hex tiles or a space station(A city, Factory, whatever)
Regional Authority control Region Tiles(which are a collection of Hex tiles)
Global Authority controls the planet.
They are then able to create polices on other organisations who use their area. For example The Global Authority should be able to set policies which affect everyone on the planet.
When Creating a New Policy
Leaders Give it a name & Description
Choose how the policy is applied(Forced, Citizens vote, Senate votes on it, city majors approve it etc)
They then pick what Policy they want to change from a list and can insert the values.
Its done.
What Kind of Policy changes should be available:
Trading: minimum/maximum price; generic tax on trading; specific tax on good or organisation; blacklist an organisation or product from trading(including galactic markets)
Production: ownership tax; tax production of a specific product; blacklist production of a specific product
Ownership: Tax on land ownership; capital gains tax; Income Tax; Death Tax
Governmental: Set regulations on voting etc.
How to avoid taxes:
Go to war with the taxer
Or leave
note:
Taxes should be applied as a markup so companies don't have to set prices based on them. They set a base price and then taxes are automatically added on top to the price.
Sorry for kind of high jacking the thread, but I think this falls under the thread tile "Municipalities and Governing System" as this is a "Governing System". If people feel like this should be its own thread I could do that.
