It’s an interesting point.
We are (tree surgeons/arborists whatever) a service industry.
We don’t make anything we perform a service.
Fallers and farmers and the like produce a product, trees as a raw material for construction etc. Or food to eat.
I can see the rationale behind thinking that is somehow more ‘worthy’ than domestic tree work.
Even line clearance keeps the population heated and out of darkness.
But then I think about the money to be made for relatively easy work and finishing early most days, I feel a lot better then.
