The point remains nitrogen can't be removed faster than it is added, at least only for a finite time.
Stated this generally, I don't see how one could consider it a useful point. In natural systems (by which I am referring to systems which proceed without intervention from humans even though humans ought to be considered a part of nature- because we are) nitrogen depletion and recovery happens all the time. It is meaningless to throw a fit just because someone is using land in a way that removes nitrogen faster than it is replenished. So what? The problem isn't that it happens. The problem is its ubiquity.
Also, the problem of nitrogen depletion, to the extent that it is a problem, isn't addressed by veganism. That's a farm practices problem, not a dietary consumption problem. Even a legume growing operation, if managed poorly, can be expected to rape the soil.
