Well, not everyone has my patience (or zeal?) for weeding. I've worked on farms, I've spent days and days manually weeding fields between plants on the rows, as well as to make fallows cultivatable. Takes time and work, but it's hardly impossible.
People tend to not like weeding, and do half-assed jobs. To win against weeds, persistence is required. Some species can actually proliferate faster as a result of botched weeding.
Rhizomes are food stockpiles. Growth drains these stockpiles. Photosynthesis renews them. You gotta deplete the stockpiles to win, which means *frequent* weeding, otherwise the leaves will make enough photosynthesis to compensate for your efforts. Seeds are of no concern with frequent weeding. Seedlings of all species are fragile. Chop that rootlet, it dies. And since it depends a lot on surface humidity, standard hoeing suffices, don't even need to pull on it.
It's the same principle for all species. Some just require more frequency than others. The only thing that differs between aggressive weeds is what will happen if you fail. In commercial fields, some of these weeds are problematic because the labor required is too expensive. But for a couple of plants in the backyard? Everyone needs a bit of fresh air...
