Re: I considered presenting

While trying to sleep last night I realized I only gave a partial answer.

Interest (what I usually call Profit) does appear in my system, but only
when selling surplus.

It might be easiest to explain by comparing it against other systems:

0. Traditional Business
The investors may or may not become real property owners.
The investor receives a recurring payout of Profit.
All customers buy the Product for a Profit.
That Profit is kept by the investors and owners as their reward.

1. Crowd Funding
The investors do not become real property owners.
The investor receives a one-time payout of Product.
Later customers (after the first round) buy the Product for a Profit.
That Profit is kept by the owners as their reward.

2. Imputed Production
The investors become real property owners and receive Product as a
side-effect of that ownership.
The investor receives a recurring payout of Product.
Later customers (when selling surplus) buy the Product for a Profit.
That Profit is spent by the owners as the payer's investment.

Imputed Production treats Profit as an investment from the payer so all
consumers incrementally gain ownership in the businesses that produce the
Products they need.
