If there are enough of these, if they actually pay the tax and if there is a will to do something within a given council - this in theory could help finance newbuild council houses. So it might not work as a deterrent, but could indirectly help those in need anyway. I don't know whether any of those conditions are true, or if the amount the greater taxes bring in would could even cover the cost of building any.
