And if my immediate relatives and I didn't ride the subway, the subway
system would still be in place and the cost would be virtually
unchanged.
So why should my relatives and I be required to pay a fare to ride the
subway?


You're right. You shouldn't. Nor should any of the other riders because
they can all make the same argument. Of course, since nobody is paying to
ride, the subway ceases to operate.

So isn't that a good argument against using marginal cost as a basis for
determining fair payment? Yet when discussing GA fees, you seem to favor a
marginal-cost assessment:

What is your share of services? What do you feel is the marginal cost of
providing services to you?
