That is intentional.  Government entities like to have a law or rule
on the books that they can use only when they need or want to nail
somebody.  99.99% of the time it is intentionally never enforced but
when the time comes, it's there to be used at their discretion. 

Other examples are the laws against vagrancy and disturbing the peace.
All governments do it.

##  I will define it for you.  Desired communications = 50 db over S-9. lol. 
If we all used just enough power to be over the noise level, we would all be
running  way less than 100w  most of the time.   The FCC has similar rules  re ssb
TX bandwidth..it has this quality wording in the clause.   Any tx bw can be used on ssb,
except here in canda..where we are limited to a measly 6 khz.

BTW, we are allowed 750w cxr on AM modes, with no limit on pep, so 5-6 x cxr is just fine,
IE:  100-150% positive modulation..using neg clipping..   And this is measured at the ant feedpoint. 
So nothing changed here on AM  from  40 years ago.   You folks got screwed on the AM power
rules with the 1.5 kw pep limit. 

Its all a moot point anyway.  Im sure anyone with a thunderbolt etc, is still running it at 650-750w of cxr.
