That argument does hold water but it would never provide enough honey for the market. It would necessarily require a vast reduction in the demand for honey to allow sustainably sourced honey to meet that demand.

In a perfect world I think this could be true. Small scale backyard beekeeping with native species, where I only take the surplus the bees themselves don't use, where queens are left alone and drones are allowed to reproduce in their own pace. The problem is: That's not how it's done on the industrial scale at all. So even if you had such a bee utopia in your backyard and could replace all your sugary needs with that, as long as the well being of bees is of interest to you you'd probably still refrain from buying products that have honey in them. In a capitalist society companies will always use the cheaper stuff, and that comes almost exclusively with massive animal exploitation.

So you are saying that instead of eating vegetables vegans should just eat honey?

Bees weren't made by humans. They can survive on their own. They work until they die out of exhaustion due to the hard work, they work because of need, not of joy. Whenever they split up when there is enough honey, they spread around. That's how bees work. By limiting them to one colony by partially starving them, we endanger the species. It's already going bad for bees, due to urbanization, perticides, climate change but also colony starvation for honey production.
