Why A Vacation Home Town Doesn't Want to Be A Vacation Hometown?

(04/09/2016) It is a new about a seaside town in Cornwall is taking on the out-of-towners (those who buy vacation homes there)?
"On May 5th, when the town votes in a referendum on a number of local issues, tucked into the ballot will be a particularly controversial question: whether to make it a legal requirement that all new housing in the area must be for principal residences only. The town expects over 1,000 new homes to be built before 2030. If the measure passes, outsiders will still be able to buy existing properties as second homes, but not new ones."

Why a vacation home town is not good for the vacation home town? I visited a vacation Mecca of New England -- Provincetown, MA several times in the past 7 years. This is what I heard from people living there about the struggle of a vacation home town.
1. Housing prices skyrocketed, natives of the town cannot afford living there anymore.
2. Increase infrastructure spending for the local government, maintaining them is not cheap. Increased property tax does not offset this new spending.
3. Increase peak- and off-season, testing the livelihood of people supporting the town's economy. If you are a plumber, you will be very busy in the peak season, but not many jobs in the off season. How do you hire workers (they will be temporary migrants too because you don't need them in the off-season).
4. Increased rent, make local businesses less sustainable. With demand fluctuation of peak- and off seasons becomes more challenging to maintain business.

I do like the idea of this town -- Cornwall. Making people who buys the home there staying there, keep local economy going healthily all year around.
