I attended my first track school (different than a track day) this past summer. We trailered the bikes there because of the distance and the issue that if one of us crashed, we'd have no way to get it back home to repair it.
Possible extra costs for going to the track:
Travel expenses (gas and food to get to the track)
Things avoided by being track-only:
State registration fees
Street risks (cars, animals, road hazards)
Theft (reduced risk)
Benefits lost by being track-only:
Better gas mileage
Riding nearly daily
I'm sure there are more, but I'm sick and my head isn't operating correctly.
