In my view there are two red herrings in this discussion: (i) the
issue of subjective vs. objective theories of economic value, and (ii)
the calculation problem.

Market prices are objectively a method of labour accounting. The
"market algorithm" is itself taking the "roundabout" approach of
labour accounting. This process is the law of value. The classical
economists were well aware of the existence of subjective preferences
for use-values. But they were interested in explaining the natural
prices that markets gravitate towards in markets for reproducible
goods; hence their interest in objective theories of economic value.
They did not deny, Marx included, that consumer preferences can be the
tail that wags the dog. But why would such considerations "vindicate"
a subjective theory of value? The weakest part of analytical Marxism,
in my view, is its attitude toward the theory of economic value.

As a computer scientist I have lots of options if I want to solve a
large system of simultaneous equations for prices and quantities given
a technique, direct labour coefficients and final demand. A less
well-known option is to numerically simulate a market, with flows and
stocks of money and goods, expressed in terms of a set of non-linear
differential equations, i.e. a dynamical system. Such a system rapidly
converges to a stable state, which turns out to be the solution of the
original system of simultaneous equations.

So markets solve the calculation problem in a distributed manner. Or,
one could "beat the market" and solve the calculation problem much
faster in simulation. The information inputs in both cases include the
level of final demand.

In my view, the more important issue of whether markets encourage
efficiency, or some new technology encourages it, is what the
socialist firm will look like, how it is financed, how its revenue is
distributed, and what democratic mechanisms exist for freeing parts of
the economy from the "realm of necessity", including control over the
length of the working day.

Alejandro, why are you "liberal" about the kinds of institutional
setups are allowed in market socialism, and why do you think, for
example, that an economy of workers co-operatives is insufficient?
