carfree roadblocks (was: package delivery)

Here's another possible risk I see in creating a carfree district: a
county trying to force roads upon the district citing some type of
"developers must build roads" law, then saying that, because they're
public streets, they have to be open to public vehicular traffic.

I sound paranoid thinking this will happen, but I feel quite confident
that we would be under a lot of fire for creating such an
"un-American" area. Speaking from personal experience, I have been
harshly criticized for:

- Not having a car [when I didn't have one between 16 and 18].
- Having a car that's too old, too small, and/or too efficient.
- Having a car and not driving it point to point.
- Living in a 1960s apartment complex with a very small,
tight-cornered parking lot that, unlike at new complexes, doesn't have
entry/exit points at both ends and allow for driving through it at 30
mph.

I just graduated from university and am looking for a better job. Once
I get that job, I can already hear it coming from family and friends:
"You need a new car now", "You've outgrown your car", "You're an adult
now", etc.

...this leaves me feeling that a carfree town of 12,000 would be
attacked for being carfree.

Any opinions?
