Anything that requires the excerise of "professional judgement" is
subject to being misrepresented for the purpose of advancing someones
individual agenda. ALARA does have a place in the radiation safety
community and must be excersised whenever the ALARA cost/benefit
analysis indicates the dose savings is worth the change. I personally
have never heard anyone state that following ALARA is not worth the
bother. My guess is that whomever stated this was not performing the
cost/benefit analysis correctly.

Here's an example from medicine:
We treat thyroid patients with I-131. Afterwards, invariably the patient
room is contaminated. The AECB (Canada's equivalent to the NRC) requires
us to decontaminate before the room is reused. The limits are ALARA
inspired, and are much lower than the annual limits for MPD in the
regulations. Because we cannot always decontaminate to these levels, the
room is often 'closed down' for a period of several days or weeks to allow
for decay. Thus we:
1 spend a great deal of time and money trying to meet the ALARA
limits,
2 lose a room, resulting in delays for admitting new patients
3 lose the revenue from the private room
There are other aspects, but hopefully this gives you an idea.
