I think the article is trying to get to this train of thought.
We want X that requires a vehicle, instead of assuming that this is a zero cost activity lets factor in the cost of parking, mileage etc.
Assuming for a moment that the total cost was an extra $200 any self respecting contra dance should be able to spread that out at $1-$2 per person.
I grew up in a musical family and spent many a weekend covering vast distances in the back of an old car so my dad could play a gig that barely broke even. Reminds me of the definition of a musician: "A musician is someone who will load $5,000 worth of gear into a $500 car to drive 100 miles to a $50 gig."
But seriously, people need to value things correctly. I spent some time on a local council and the shopkeepers would be up in arms whenever they thought they'd lose a parking spot, despite every census showing most of their customers walked to their stores. The shopkeepers viewed the parking as "their parking" and not "our parking" (As in the community). Yet for some reason the footpaths were most definitely "ours footpaths" (The council's) so repairing or even cleaning them was the Council's job, and heaven forbid we suggest the shops pay towards that cost.
Its common in Seattle for the city to do basic maintenance on a sidewalk, and bill the property owner for the amount, as they failed to maintain their sidewalk (whether Ivy has overgrown the sidewalk, roots have uplifted it, or its become a public health hazard due to lack of cleaning).
It is really nice to walk on freshly steam cleaned or pressure washed sidewalks :P
I recently played for a contra dance in Manhattan. My band members and I drove in a small car, with a sound system, keyboard, and other instruments. I would have been happy to pay some sort of toll/charge/fee/tax but any other way of getting our equipment to and from the gig would be far more expensive and a lot of a hassle.
