Apparently if you let them grow initially to exhaust the fuel from the stored tuber you can then simply pull up the plants and that takes care of it.

Are you saying that if I harvest a 10'x2' patch of tubers in a given spring, that I would be unable to plant in that space? After one year of planting annuals there, I would plan to let the tubers take back over. Is this not possible in your opinion? My soil is very shallow and lacking in needed structure so I'm guessing it will not be as unruly as it is in your garden, this is montane ponderosa pine ecosystem at 8400 feet above sea level with 6"-2' of soil on top of rock mostly. Frankly if any useful plant grew really agressively up here, I would consider it a big win. But I do plan to contain it between 6' wide paths in case that's a possibility.
I know I would miss some, but that's part of the plan. I see your point, but much of what you said is why I want to use this plant. It doesn't seem like it would be an impossibility. Is that what you are saying?
