Do you consider Gerard 't Hooft also one of those non-technical people? Mocking the use of certain diagrams does not give you any credit. I would refrain from such petty arguments if you want to be taken seriously.

About your argument, as far as I know, the measurement problem is not solved in QFT. I have also never heard of adding a term to the Lagrangian to represent a measurement. The addition of the external field to hamiltonian of the atom when calculating the Zeeman effect is something unrelated to measurement afaik. If you have any references on your claims please point them out.
