I agree with this, but in practice often the underlying problem isn't known, and has to be determined through a long process of trial and error. During which the plant mass that has to be discarded because it's too far gone can add up so quickly, you might as well have torn it down.

A couple of personal examples, which I only found by trial and error because they were contrary to common sense and advice:

1) Once for three months I struggled with algae, with everyone consistently saying I should decrease light, which only made it worse. In the end, it was completely solved by increasing the light.

2) This treatment was originally developed to deal with my oddball staghorn, which is resistant to H2O2 or Excel alone, and grows explosively if you give it too much flow. It was solved in the long-term by reducing flow, and/or redirecting it away from plants, but it took months to figure this out.

So a good chemical reset will always be a valuable tool.
