Caveat emptor simplified commerce by discouraging litigation

Evidence

But caveat emptor did have a certain ideological appeal. And it does enhance the finality of bargains. It discourages parties from dragging into court harangues over warranty and quality. This is what Gibson had in mind when he spoke of the “terror of endless litigation.” A clear, harsh rule, he felt, was necessary. For the good of the flow of commerce. Whether these rules (or any rules) actually had this effect is another question. — Lawrence M. Friedman, A History of American Law, 1576
