Sure. I have in mind very specific, but very numerous cases where I live, in Luxembourg, where the frictions induced by laws and regulations and the centralized monetary system leads to a suboptimal situation where A needs a good or service that B can provide, and B would be very happy to provide that good or service at a price that both would consider "a good deal". And yet because of the intermediaries and their "cuts" the price raises so much that A is not willing to pay anymore. The transaction doesn't happen, B cannot earn money and has to leave, the "supply" he was bringing disappears. Everybody ends up worse off.
