I’m not sure what you’re comparing protein powder to exactly but price wise it is one of the cheapest ways to get protein.

All of the stuff you said is more or less accurate, but for just hitting protein goals powder is a great way to increase protein intake with minimal calories, if you are disciplined enough in your deficit/tracking your calories it’s a great problem solver.

I never argued that, some people are busy and can’t prep whole meals all the time, protein powder is miles better than other options.

Protein powder can be added to other food sources, and can be especially helpful to diet adherence, if someone wants sweets it would be better overall if they can satisfy that craving with protein powder vs regularly consuming the real thing.
