&gt;Why is it that companies with fixed payrolls, buildings, etc., exist? In a fully marketized world, we would contract, daily, with providers for all services, including day-to-day secretarial services, copying services, coding, document and report production, research, everything.<p>I don&#x27;t find that compelling at all.  There&#x27;s no reason to think pricing needs to be done daily, or that cost can&#x27;t be aggregated.  You could only consider this the &quot;supersession of the price mechanism&quot; if you believe your time has no value.
