I think there's some misunderstanding going on. The argument you critique is: "In a market, goods go to those with the highest willingness to pay. Hence the resulting allocation is socially optimal (according to some social welfare function)". I don't think anyone in economics makes that argument. The only claim is that allocations that result from a market are Pareto efficient (under some strong assumptions, which I'm sure you're familiar with. See the first fundamental theorem of welfare economics). Again, the real question is: if not markets, then what?

but people in economics do make the argument that charging prices such that supply and demand are in equilibrium improves allocative efficiency.

Relative to what?

relative to charging prices where demand is in excess of supply

for the reasons i explained above, i think many economists believe this is true (in many situations). But they don't use the argument you attribute to them to do so.
