Most do not keep bees because they are making money, producing much of this or that, or doing anything but enjoying the bees. Its a love affair, it's a hobby, it's something they enjoy, regardless of what happens through the years.
I think TBH's for many just adds a new twist of interest. It's something to enjoy.
I find the natural comb interesting. I like to try everything in beekeeping once. When I have nothing new to experience, nothing new to build, and nothing else to gain, I'll probably look for something else to fill my time.
