Sure, but when you increase power and airflow, you also increase juice consumption. Then the question becomes: If someone can stay off cigs by vaping (for example) 5 ml of 18 mg a day at 15 watts, is he really gaining anything by vaping 15 ml of 6 mg a day at 45 watts? IMO, the answer is definitely no, because the total nicotine intake has not changed, while the amount of other substances (PG, VG, and flavorings) inhaled has increased by a factor of 3.
My feelings are mixed about the above statement.
I go through a lot of juice. I vape at 18 to 22 watts, use coils in the range of .5 to .8 and do go through a good amount of juice. I use 3mg juice down from 50 when I first started vaping but on different equipment. My overall nicotine consumption -not absorption -, based on the amount of juice I go through, is definitely high, but overall less than the overall amount of I used when I smoked.
There are so many studies and papers about how much nicotine is actually absorbed via smoking and by vaping but nothing that I have found that is totally concrete -- just educated estimates.
This one (source
Government Laboratory - Tar and Nicotine Report) discusses the nicotine yield but not the total and then cigarette manufacturers had to change the labeling from the method they used and only use the yield (source

The key difference I believe is the number and type of ingredients, There is much less in vaping and, of course, no tar and no burning tobacco.
In my case, I am one of those folks who smoked a lot and now vapes a lot so decreasing the amount of nicotine substantially did not increase the frequency for me so there is a benefit to me at least. It's not like I get enough nicotine and then just stop for the day.
I know that when I smoked if I bought a lighter cigarette I could smoke 3 times the amount and not be satisfied and so, far, that has not really happened to me with vaping - although it may have if I dropped dramatically all at once.
For me, I've noticed that I no longer easily get winded as I once did and most importantly I do not feel the same dependence. I've noted that I can go out without my vape and not feel "crazy" and, although I vape regularly and, even in the morning, I generally do not open my eyes and stick the vape right in my mouth. I can also stay in a non-smoking or vaping hotel room and not freak out and run outside if I could not vape for 8 hours.
So, I think that even with a fairly overall high nic content and likely absorption I am still way ahead of the game.
