I actually think he's right that there should be no status of any kind at the security checkpoint.
With things that have to do just with the airline, status is all well and good. But the security is something that everyone pays equally for through their taxes, and it's a government function. Why should the government prioritize some people over others based on their FF status? Also, just in principle airline security is one of the burdens of maintaining civil society, so ought to be shared equally by all.
The government is not providing prioritization to elite flyers. The airlines, who pay rental fees to the airport for the space prior to the TSO performing the TDC, have chosen to provide a priority line in THEIR rental space prior to the TSA checkpoint. That is their privilege, as it is THEIR rental property prior to the actual TDC checkstand. Once you have passed the TDC, you are in TSA-land and are subject to their decisions on which queue you end up in.
