I agree with the first part of this, but the truth is he does need the gear to do what he's doing; for better or worse, if you're going to be challenging superhumans, some kind of edge is needed. Even Nat and Clint aren't trying to do it with their skills and conventional gear.
But that's the point: anyone can use gear. It doesn't need a superhuman to do that. Rodey isn't a superhuman, Nat wasn't, Clint isn't, and Sam doesn't need to be; he needs to have the personal tools he has, and the external tools he can get.
