Technically you are correct, in practice, not too much. Generally a purchase like this is done as is. It's up to the buyer to confirm it's useable. Another legal way to steal is done by shady businesses all the time, they buy stuff they have no intention or know they could never pay for. If you go after them they go bankrupt. Nothing you can do about it, except be diligent and limit your exposure up front.
Right after our business sold we had a customer, who had been ok at paying, suddenly get very slow, they got into us for about $50k. It was partially my fault because I knew one of the guys in charge, who all of a sudden became very unresponsive. Their problem was that we were holding about $500k worth of inventory we used to make their product for them.
They were over 100 days past due, unresponsive, when they called and placed an order. I told my inventory guy to grab all their inventory and bring it to me. I locked it in a cabinet. I told the sales guy to call the customer back and tell them that we can't find their inventory, sorry. They all of a sudden got very responsive. The guy I knew called me yelling and screaming telling me it was illegal to hold their product hostage, he was going to sue me, blah, blah, blah. I told him that we weren't holding his product hostage, we just couldn't find it, but it didn't matter anyway because we weren't lifting a finger to find it until they paid in full. A bunch of calls and about a week later a check came for the full amount. He called and asked when the product would ship, I told him 'Good news, we located your inventory!, but you are now Cash in advance, we'll turn your order as soon as the check clears. They sent a cashier check that day, told me to include all their inventory when we shipped. We obliged. While this was going on, I decided to "retire" and had given a months notice. The guy I knew called my "boss" and told him what had gone on and we had lost a huge account. The sales guy was upset because of his potential commission. My boss called me and asked what happened, why did we lose this huge order. I told him that he should be thanking me, I just saved us a $50k write off, that the guy I knew was full of crap. I did my notice time, left, about 2 months later the customer went bankrupt, with about $15 million in accounts payable to a bunch of companies. The CEO got a million dollar severance, the guy I knew get screwed out of a months pay. I just laughed, called my old boss and said, "you're welcome".
