Well, believe it or not, blackouts work quite well ;-)  

So does manual labor.  Like algae in a planted aquarium,
keeping after it is much easier than trying to catch up. 
In fact, this tends to be the most effective in flower
beds, imo.

Tolerance is another method, but it's a matter of taste. 
We go to the nursery and spend a small fortune on flowers
and then despise the dandelions on the lawn that look,
well, pretty much like the nursery flats.

If so much is alredy being used, is that a reason to use
more or less?

It's not a question of logic.  It's not a formal
contradiction to use one method instead of another.  NO
more than it would be formal contradiction to use UGFs or
flower pots and no aquarium substrate.   Perhaps you mean
to argue that herbicides are the most *convenient* or most
*practical* or *financially feasible for a commerical
enterprise given prevailing labor rates."

I don't I like them all.  Well, I guess I should say, I
don't know any of them well enough to hate them.

I think most people mean by "weed" something like "a plant
that flourishes but is in the way  and not wanted" and
often by analogy to that, anything with those properies.  
Often it is used as a referring term rather than as a
pedicate (without intended description) and the referrant
is an item that folks in that linguistic community often
refer to with "weed".  But there is no law about how words
are used -- if there were, I fear country music songs and
tabloid headlines would have fewer puns.  

Now I gotta go spray to kill the deer ticks.  They grow in
the woods like weeds this time of year.

Generally, when I use it, I am referring to nutsedge or
poison ivy or both, depending on context.

If I had a pond, I don't see why not.  It's conventional
use of the term.
