Ever attempt to do a particular calculation with an actual infinite dimensional Hilbert space? Why not? Sure, you can mod out (using symmetries and other tricks) all of the infinite dimensions except some finite subset, but that is the act that introduces the bias that I am pointing at! The actual Hilbert spaces used to do calculi are finite dimensional. No, Choosing a basis and choosing a coordinate system is NOT a convenience. You must do it. Especially in GR, where one cannot define the manifold unless there is a choice of coordinate system on the patches of local space-time used to define the manifold - which is then run through the diffeomorphism mill... AFAIK, there is no global manifold that can be defined that does not involve the requirement of stitching together of local patches of space-time (defined per individual events) into manifolds of arbitrary size. What must be remembered is that the "stitching operation" is very restrictive, one cannot connect patches that have events with different (other than an infinitesimal) values of momenta and position associated with each. The math of GR is amazing once one is familiar with it...
