Good answer. I'd add that section 137 has restrictions that would almost certainly preclude its use in this context.The expenditure must be such that it "will bring direct benefit to, their area or any part of it or all or some of its inhabitants". That implies not a single individual. Section 137 also requires that the benefit from the spending must be "commensurate with the expenditure to be incurred". I wouldn't think that taxpayers would consider that to be satisfied in this case.
