Re: Treatment Free - How long does it take?
I want to point out, first, how general this statement is. What you are saying is: ' at no place, under any circumstances is sufficient breeding pressure being bought to bear. You go on to out what you would consider to be sufficient breeding pressure, choosing a starting population of 150,000 individuals, and selecting at a rate 1:150.

a) You are, again, arguing for the creation of a 'fixed' trait. You heard my argument before: in relation to defences against a predator, no such thing is possible. That isn't how nature works. Prey and predator are in a constant 'arms race', each evolving to try to maintain its advantages. Selective pressure must be maintained. The price of health is constant selection.
b) Not all places are the same: in some location feral and/or tf beekeeping has already raised varroa resistant traits to a largely satisfactory degree. We hear, often from, and of, beekeepers who are succeeding by working with the grain of natural selection.
c) Your figure '150,000' is arbitrary, conjoured out of thin air simply to try to give force to your argument. That won't work. Note that any resistant bees emerging from such a selection process would, if exposed to artificially maintained genes, still have to be continually selected for mite-management behaviours.
d) All apiaries (all stock-rearing operations) must continually select to maintain health and productivity. In a tf apiary, this necessary process automatically selects the stronger mite managers.
What you've done is defined 'breeding' by your own criteria as a highly intensive and controlled process, well out of reach of anyone but a huge dedicated breeding operation, and taking the view that anything less is pointless.
That position isn't sustainable.
Here is a position that _is_ sustainable:
"The more undesirable traits are excluded from a breeding pool, the less they will appear in subsequent generations."
That describes the underlying rationale for healthy stock-rearing, and, as a statement, its bulletproof. And it is incompatible with your statement. Only one can be true.
It applies to all operations, anywhere, from the largest to the smallest. Of course in very small operations, due to open mating it will be difficult, and perhaps impossible to achieve - that will depend on the traits carried by local stock.
You've set up a straw man - the notion that only high intensity breeding will produce worthwhile results, and then used that as the premise for your justification. It won't wash. Low level systematic selective propagation can - and must - be regarded as a breeding activity; and like all breeding will make progress according to the quality of input stock and the skill of the breeder.
Its up to you to ensure that selective pressure is bought to bear. That's the skill part. Find a good spot and build a mating station. Inadequate resistance will only prevail only to the extent that you do your job poorly.
