Earlier quoted context omitted.
Near-peer conflicts have more meaningful targets which favors these kinds of expensive weapons platforms. A drone that can do meaningful damage to a factory 500+ miles from a front line is either an easy target or it starts to look a lot like a missile with all the associated costs from that.
I think it's more complex than that. The US made Switchblade drones which cost tens of thousands of dollars were outperformed with lightly modified FPVs with grenades, which came in under a thousand.
Leave the realm of mass production and you can build drones that would be, but they quickly start looking like existing systems because militaries have been working with drones since WWII.
