The problem is that some smart Alec will sell you 5
Elbonian
yards (but the Elbonian part will be in really small print, in
white ink on a white background). Weights and measures have been
regulated in various ways, in various places for a long time.
The only thing that's changed recently is the units that can
be used. A free-for-all will just let the con merchants thrive
and that's bad for all of us. So your only objection is that
they can only sell in one system instead of two. There's not
a great deal of difference between 5 yards and 5 metres ...
it's only going to be rapidly yanked off a reel, measured
approximately on the wooden gauge by the reels and
then cut approximately. In our local shed you get to cut yourself
and declare a length at the checkout ... must remember to try
declaring a fraction of a furlong some time :-)

I think we should adopt the Weights and Measures system proposed by The
Register:
