Sounds like the regulatory environment was an investment risk that wasn't taken into account.
Persistence in regulations isn't some sort of right. Laws change all the time. Any investment made without considering the risk of the anti-NIMBY movement is no different from any other un-diligenced investment -- foolish.
Holding an asset and concerned about the risk of diminishing property values in the face of shifting regulations? Unload. You'd do the same if you're seeing a company where you're Long run into potentially difficult headwinds.
