Any company can take barter for their services if they wanted to.

They'd have to be pretty dumb to take a normal quarter as barter worth a whole mortgage instead of 0.25$ though.

Generally barter relies on the good being a similar value, whereas sovcit logic tries to force them to take terrible barter through the magical contract system america is beholden to, because obviously an all-encompassing contractual indentured servitude will have easy cheat codes to break out and get paid while you do.
