That's great if they can sell it and make money to subsidize the other part of their business (pollination). But if the economics aren't there, that's unrealistic.
Remember, honey bees harvest honey as food for themselves during winter. If you take away their honey, then you need to feed them sugar. The most practical thing is to leave the honey for the bees, and make sugar for humans from other sources that are cheaper (can, beats etc). If honey has some amazing benefit for humans that can't be replicated (whether flavor or health), fine, but the fact that so many can't tell the difference tells me that that isn't sustainable.
This is only in some parts of the world. My bees have never known winter.
I think you're missing my point but I don't have time to elaborate.
Even without that usage, harvesting honey can be harmless to bees and benefit surrounding plant life. That makes it one of the best (if not the best) sources of concentrated sugar from an environmental perspective.
