No. In many places Zoning changes do not happen unless you know somebody or have really expensive lawyers. Getting permission to build a house even on property zoned for such is about as likely as the zoning change. Travel around the country and see how bad it is in some places.
Why would traveling enlighten one to zoning issues? I've lived up and down the East Coast. That doesn't mean local zoning ordinances are learned.
If property drops to a few hundred an acre, I'm sure zoning will become more workable. Everyone needs to make money. Property and building will be an incentive.
