your also in probably one of the most heavily populated amateur radio use 
areas of the world.
Even when I was at the seeing eye in NJ, I couldn't believe how many 
overlapping coverage repeaters were on the same frequencies.  RX tone just 
makes sense in those kinds of conditions.
I couldn't believe how many people were on 80 and 75M at night 
either...there were groups every 5KC's right across the band.
In my region we have about 2 main frequencies and perhaps 30 different 
regular operators on 80M.
Then again, the tri state area has a larger population than the entire 
country of Canada.  Add in some of the other eastern seaboard states with 
massive populations in when there is a band opening, and i can imagine how 
it would get kaotic without rx tones on your radios.
