I only chimed in on this because I know there are some that will bash giving up treatment free and I wanted him to know that he's not alone!
My view is when it is your money being sent down the rabbit hole, you get to decide. No problem with that. When it comes to blame of why a decision is made, it is not always clear of what is going on. Some people have higher winter queen loss or bad queen return during mating flights. When we start thinking about possible causes of such things, it is hard to know for sure the why. Was it due to varroa stress or poorly mated queens or poorly made queens or many other possibilities. Since all these things are not like, the queen fell off of the frame and I stepped on it, which could be seen as it happened, conclusions can be hard to be sure of.
So if we do not contest that other people are keeping treatment free bees successfully, then the why of it not being able to be done by him is a muddy thing that might be hard to point a finger at true cause. It is a big system that one small thing might be throwing off the working or it not working. It is just like my area where it is working, One virus mutation and it might not work for a bit. I see this with deer populations. I do not believe there is any silver bullet or pill that makes everything work every time with live things.
So, I never question how somebody keeps their bees alive. They are the ones spending the money and doing the work and so they need to do what ever they have to to get something back for what they put in. I do not question it at all as long as I am not questioned on what I am doing and what I know is working with out guessing cause I see it. To me it goes like this. Get bees, watch them and respond to them till you have success with them. Don't worry about all the things out of your control but more just watch how your bees are affected and respond. When you have consistency with life, change only small things at a time so you can see what those small things do in the big picture. When you get to where you are happy with what you have, repeat. While repeating, watch for those changes that are out of your control and respond when needed.
If he keeps having good luck that he is happy with by treating, then he is happy no matter what I might think. I might still think it is possible to keep bees in a different way but even I might not want to pay the price to do it if i was happy already.
I am not bashing what he decides is good for him. I do see around me that there are a whole bunch of ways to skin a cat and that they are all in the same place and doing things different from each other and some just seem to be good at it and some do not regardless of the how they try. The ones that are doing real good treating, know they are doing real good. The ones doing real good with out treating, know they are doing real good. The proof is in the pudding.
