I think the insight is that you need a high-low mix. Some threats call for top of the line capabilities (like early days of the Iran conflict with stand-off munitions and top-spec interceptors being used against Shahed drones and cheap cruise missiles). Some threats can be more economically serviced by a less capable, cheaper, and more available system.
100% this.
It's always been about the biggest, fastest, longest range punch. That is extremely useful for deep strike (which has always been NATO doctrine), but when the range is short you need quantity and mobility far more than you need quantity.
Being able to cut off your enemy is an extremely effective weapon if your enemy needs massive supply. Drop the major bridges between Moscow and Ukraine and the war would soon be over.
But when you can't do that for whatever reason you need quantity and mobility far more than you need quality.
I mean the armed forces already know this well. They have a bunch of units of regular soldiers, and then they have a few special forces units.
Ukraine is using old school propeller trainer craft to shoot down some of the slower Russian drones. https://theaviationist.com/2024/06/26/ukrainian-yak-52-kill-... There's usually new footage of this every week on social media.
Don't really see or hear about the USA building or using propeller driven planes in military outside of special ops.
