The number of people who use state and federal parks in a given year is roughly equal to the number of people who fly.

It’s definitely a few notches above “very few”.

I wonder if the parent to this comment is another "I don't use trails, so no one does!".

If you actually walk along a few trails on a regular cadence, it's clear that there are many different people - it's not just the same people every weekend.
