The optimal economy and the maintenance fee
The joint viable set is not a single number. Food, shelter, health, education, mobility, ecology, trust, time, security, agency. An index is a projection. The set lives where people live.
An architecture with high output and a room narrowed by parasitic accumulation is narrower than one with lower output and a wider room.
Taxation is the structure’s maintenance fee. The structure supplies conditions — infrastructure, correction, governance, the dignity-floor, protection of unpaid capacity. They cost. Tax distributes the cost across those who benefit.
Extraction takes from someone who receives no conditions in return. Maintenance is contributed by someone who does. The difference is the relationship, not the rate.
A cooperative pattern reads four things. Benefit received. Capacity to bear the contribution without falling below the floor. Accumulation the structure’s conditions produced rather than the holder alone. And external cost the holder has been pushing into the room. Benefit without capacity is extraction from the already suppressed. Ignore external cost and parasitic propagation continues under legal cover. Exempt accumulation past the threshold and the fee is parasitic from the other side.
Tax needs the same three conditions law needed. Readable. Contestable. Audited.
