I'm sure you can find specific farming practices that are beneficial to bees, but I don't think you can make a good faith argument that i.e. pesticides are the reason there are large numbers of bees.
No one is arguing that we should throw out all of modern farming practices, so there's no need to jump to their defense.
Can you expand on this? I've been thinking about getting a hive and coincidentally was wondering about this earlier today -- can you let a hive swarm without losing it? I.e. does a spritely new queen take half the hive with her? Is it healthier for the hive to do so?
Now about hive health. There is this thing called Varroa and if you let the hive swarm half of it goes with the swarm and the other half stays. Varroa I mean. What is really good with swarming is that the hive now has a virgin queen and she doesn't lay eggs right away and a lot of Varroa dies off because they can't reproduce. They need eggs and bee larvae to do so. The swarm with old queen has an interruption as well because they need to build comb and cells where the queen lays eggs.
In my beekeeping years ago I kept hives healthy ( fight against Varroa ) entirely with letting them swarm.
Just to write it once again since by your writing I think you are confused...Old queen leaves with the swarm.
Although I must say that natural swarms show greater vigor when building new comb than splits. Even packaged bees built faster than splits. That is of course my experience and you have to keep in consideration that I didn't add any foundation to new colonies so that was maybe one of the reasons. I let them build their own comb on a narrow strip in the frame/top bar and never tried with full foundation.
We may be on the edge of a new wave of a more organic farming, on a mass scale. Using plant communities and synergies to reduce or need for the more simplistic, mass application of chemicals.
Without even getting into all the genetic engineering and the like that is sure, however you feel about it, to continue.
If you have a bot passing through every couple of days, would they continue to visit the rest of the field where the bot is not currently present?
Very interesting factor to consider and be concerned about.

I can't find a great page to link to, but this has a decent, short description of what they are doing:
https://www.forestag.com/pages/mark-shepard > Trees, shrubs, vines, canes, perennial plants and fungi are planted in association with one another to produce food (for humans and animals), fuel, medicines, and beauty. Hazelnuts, chestnuts, walnuts and various fruits are the primary woody crops. The farm is entirely solar and wind powered and farm equipment is powered with locally produced biofuels that are not taken from the human food chain.
The part that interests me is, they can grow half as much of a crop per acre as a monoculture, but they can do it for like 10 different crops in the same area.
And they don't have to spray it with poison, so there are cool things like tree frogs out there.
There had been more competing pollinators.
The almond is a species of tree native to the Middle East, the Indian subcontinent and North Africa.
The narrative that somehow pesticides are bad because they unatural is disingenuous as it forgets that every part of this system is artificial.
