Edit: Changed title to be more accurate.
Also here is the summary from Wikipedia on what Post-scarcity means:
Post-scarcity is a theoretical economic situation in which most goods can be produced in great abundance with minimal human labor needed, so that they become available to all very cheaply or even freely. Post-scarcity does not mean that scarcity has been eliminated for all goods and services but that all people can easily have their basic survival needs met along with some significant proportion of their desires for goods and services. Writers on the topic often emphasize that some commodities will remain scarce in a post-scarcity society.
I thought your plan was simplifying things and getting lawyers out of it, guess not.
How is a fair mathematical formula determined? Who decides what is appropiate? Are sales the only metric for the formula?
The inventor licenses the patent for for an agreed upon value. Value is determined by the market.
See above.
How are those not addressed?
Money that goes to patent holders is a patent fee no matter how the money is collected. If a company uses a patented invention but doesn’t list it how is that infringement enforced? More lawyers and lawsuits?
Details are the important part, how is the value of one patent determined over another, ie how do they split the revenue.
