A GA owner can choose to invest in ADS-B-IN. If the owner does so, the

exactly what is the cost of that benefit? Shouldn't the GA pilot
(alledgedly) benefiting from ADS-B Out not fund the equippage of those
aircraft with ADS-B Out?

Did you write "out" where you'd meant to write "in"? Otherwise, I'm
afraid that I'm not understanding your question.

GA pilots aren't funding equipment in other aircraft. They are, however,
funding the creation of a network in the air whereby all aircraft
(excluding military? Nasty, that!) are announcing their positions. It's
not all that different from transponders, in the sense that putting a
transponder in an aircraft benefits all aircraft, and not just the
aircraft footing the bill.

Separate from this, the GA owner can choose whether or not to spend the
extra dollars to gain direct benefit from this network.
