Because we know that network capture is an absolute, unquestionable requirement in order to defeat adversaries who are both prevalent & who can actually be defeated. 

There's no talk of 'privileging' anything. The talk is about not arbitrarily depriving network administrators & security personnel of the tools & techniques they've been using for many years and with great success to troubleshoot & defend their networks, applications, services, & data.
