The CDWS and the mystery of the 60-tanks-rule

According to one of the CDWS-rules, each and every dive center needs to have at least 60 tanks.
Hmmmm....
What about Dahab?
Have a look.....
In Dahab, there's a lot of small dive centers, maybe hosting only 2 - 5 divers a day.
Why do they need to have 60 tanks?
And why do they need a compressor (another CDWS-rule?)
Where will be the filling stations?

And, by the way: Do you know how much it will cost to properly maintain a compressor?
What will be the result? Badly maintained compressors will lead to bad air and will lead to the death of a couple of divers....that's one (cynical) way to close down the small dive centers.

If there's a dive center with less than 60 tanks (yeah, please check all the dive centers which are 'owned' by Egyptians, apparently they don't need 60 tanks) why can't the dive center teach courses?
Do I need 60 tanks to supply 5 divers?
The CDWS couldn't answer yet!

Yeah, let's kill all the small and nice dive centers...Thank You, CDWS!
