Once you prove to DWP that you are entitled to PIP and they award you a sum of money, that money becomes yours, end of.
Just like Politicians who get paid a wage out of the public purse once they receive their monthly pay (not expenses) it is no longer tax payers money but the MP’s. All members (800 of them) in the House of Lords can claim £300 a day in much the same way as we receive PIP but not one of them would regard it as tax payers money once it is in their bank account. The phrases like tax payers subsidise housing (people that rent social housing), tax payers subsidise car scheme (people who use Motability), tax payers subsidise wages (people who work and claim tax credit) etc, have all been used by The Daily Mail and Express who’s readers have no compassion or consideration for others who are less fortunate. I have no problem claiming money which I am entitled to and calling it mine to do with as I please because that is exactly what it is MINE
