In theory a reasonably skilled individual should be able to recreate your invention from the patent. In reality patents rarely provide sufficient details to do so. The fix is to bring reality back in line with theory.
So nobody should be an inventor unless they are employees of a corporation that can afford to commercialize everything they make?
What does the patent even do- protect the rights of the most successful company? At what point does it get taken away from the company that couldn't make enough (what's the dollar threshold?) and to which company is it given (or do they all just use it at once, and then the most successful is awarded the patent, and the rest have to pay arbitrary licensing fees to the winner?)?
Patents exist to reward research or invention that results in practicable ideas. Entrepreneurialism is not (and should not be) part of that.
