The fact that recent engagements have been within easy drone range is an accident of geography. The same situation won't necessarily obtain in the Western Pacific. The quantity of drones you can produce won't matter if the launching platform can't survive long enough to get within range of the target.
This gets complicated, because technology usually advances on multiple fronts at the same time. As others have mentioned, we've seen drones primarily used as an air-to-ground weapon in Ukraine because the airspace is not particularly contested. We have not yet seen them used in air-to-air combat.
There are multiple reasons to believe that drones' advantages over piloted aircraft are even greater than drones' advantages over tanks. Take the pilot away and the G-forces you can pull increase many-fold. Take the pilot away and you have no compunctions against sacrificing a drone for tactical advantage. Take the pilot away and you can field 10x or 100x as many aircraft, since pilot training is often the limiting factor in the growth of your airforce (see eg. Japanese WW2 experience from 1943 onwards, or the need for Top Gun in Vietnam). More aircraft can play airspace denial, since the presence of a bogey creates a kill zone in the area where they can bring their weapons to bear. Computer algorithms can play physics and geometry games where no matter where a piloted aircraft turns, there is always something waiting to shoot them down. Computers can run these simulations instantly, overwhelming the pilot's ability to react. The human becomes the weak link in the weapon system.
The equilibrium I see is drone designs with a range made to just out-range cheap weaponry like glide bombs and common anti-ship missiles, maybe 50-80 miles. For anything fancy (like the supersonic cruise missiles that the Russians have with 200-300 mile range), you want directed energy CIWS instead, but you need those anyway to defend against enemy drones. Then you pack these drones into shipping containers, and launch and retrieve them directly. A single container ship carries its own air force of roughly 10,000 drones, and makes the airspace around it out to ~100 miles completely inhospitable for foes. The convoy becomes its own aircraft carrier, just like the escort carriers of WW2, but the air wing follows the shipping containers and can be packed onto trucks or rail at its destination. Then you bring the convoy to where it needs to be, creating a no-go bubble around it at all times.
Yeah, although given the number of TEU shipped from China to the US, I would not count out a significant number of drones having been prepositioned in US territory.
