Violating a random municipal zoning board’s orders by building something without the necessary permits is a clear cut violation that is easy to spot that you cannot use plausible deniability for.
The US is not that corrupt yet. The billionaire might be able to bribe the zoning board members, but it would be pretty sacrificial of one’s self to risk a felony just to watch the building’s freshly laid foundation get destroyed, because that is only how far one might get without the cops getting involved.
