I suggested a solution before in another post.

If money is truly no object for PIF and the concern/excuse to stop us and others spending to challenge the cartel/PL is the risk if owners doing a flit and leaving a club in massive debt then why not lodge a rolling amount equal to the clubs liabilities annually into a collateral/credit cover account that the PL can access. The figure would still belong to the club but risk is eliminated.

It solves the problem.
