While I agree that we fall well short of the utopian ideal (rather than the farcical interpretation) there are plenty of other bureaucratic barriers to meritocracies as well.
In my experience even the most dedicated, agile people hit organizational limits on complexity or continuity and ultimately have to settle for sub-par network topologies, software stacks, and yes even coworkers.
To the extent that we all understand a meritocracy to refer to a system where things are evaluated on their merits, hopefully all agree that it is a fine ideal even if the historical meaning (like 'begging the question') is different.
