By producing, then, he necessarily becomes either the consumer of his own goods, or the purchaser and consumer of the goods of some other person. It is not to be supposed that he should, for any length of time, be ill-informed of the commodities which he can most advantageously produce, to attain the object which he has in view [anticipation?], namely, the possession of other goods; and therefore, it is not probable that he will continually produce a commodity for which there is no demand.... Too much of a particular commodity may be produced, of which there may be such a glut in the market, as not to repay the capital [funds] expended on it; but this cannot be the case with respect of all commodities."

You're too quick to declare "victory" here, Daniele. The person who
produces more than he anticipated would be bought at current prices
would face the choice to lower prices and clear the excess -- in the
short run. Or else, as Ricardo also explains, he may hold on to some
unsold inventories and borrow funds to sustain his own desired level of
consumption. That increased demand for loanable funds would the cause
interest rates to rise. The rise of interest rates would put pressure
on the seller quickly to decide to reduce prices or reduce the rate of
production. But the important point to note is that the excess supply
causes prices to fall while the excess demand for credit (than formerly)
causes interest rates to rise -- in the short run.
Say's Law or the law of markets is about the interconnectedness of all
markets for produced goods and services. It explains the causes of
changing relative prices and interest rates from changing excess
supplies and demands. You incorrectly seem to think that it does not
apply to situations of disappointed expectations such that the rates of
production may decline (and unemployment rise) or prices fall or losses
are made. This is how Keynes thought that the Great Depression was
proof of the invalidity of Say's Law. But he was wrong.
