If everyone is overpaying tax, that's OK, you can just adjust the tax rate.

I think the real issue is whether is promotes certain uses of land over others, and whether that's problematic.

Everyone overpays, but they overpay in proportion to how sticky their business is to a specific property. It would take someone who knows more about commercial property to dissect what businesses would get destroyed by that.
