We describe a general principle of completeness in QFT. It asserts that the physical observable algebras produced by local degrees of freedom are the maximal ones compatible with causality. We elaborate on equivalent statements to this principle such as the non-existence of generalized symmetries and the uniqueness of the net of algebras.
