No valid philosophy can't be practiced to the nth degree. If a philosophy must be tempered by pragmatism then it is not a valid philosophy, it is sophistry.
Sophistry deserves base rejection. Does Chomsky have a valid philosophy? Ideological alignment with anarcho-syndicalism yields no valid philosophy. Alignment with libertarian socialism yields no valid philosophy.
Anarcho-syndicalism and libertarian socialism deserve base rejection. Those with no valid philosophy invoke sophistry to appeal for undeserved respect for what they posture as "nuanced" indifference to truth, often while petitioning statist initiation of aggression, simultaneously clinging to pragmatism (aversion to principle) as an entitlement construct.
Anarcho-capitalism or else, and you already have the "else". What you don't have is James Corbett, and I suspect you never will. The real question arising is why do you desire to have him?
Save yourself.
