I think I may agree with that too. For sure, I have no use for an optimizer, and the ML system I use is, in my opinion, both more elegant and significantly simpler than most.
You certainly make some great points.
I’m not even sure the optimizer is included in my current P123 membership level, if your point was largely about the pitfalls of optimization. Even fast, automated optimization has significant limitations with present-day computers, and I’m not holding my breath for quantum computing to solve that anytime soon. 
A broader point that might just be mine: compute limitations are often a bigger problem than they first appear—especially when trying to use a large number of features in a model. Some form of simplification is required much of the time, and essential if you want to explore the entire solution space.
