I always felt P.O. boxes should be free for those that are homeless. If said box goes unused it is put back into general use.

They (basically) already are. USPS provides free mailing service for people who don't have a fixed address, and you can use that as your street address (unlike PO boxes, which are invalid for use in circumstances that require a street address). They'll hold onto any mail addressed to you for 30 days.
If you, heaven forbid, ever become homeless:
If anybody ever insists that you provide a 'real address', lie. List your PO address as "123 Street Name, Apt #PONUMBER".
Nobody will ever be assed enough to check that it's not a real apartment. Nobody.
There are private PO boxes you can rent out, instead.
