A couple of inches is transformative. You go 14" arms to 16", with no change in bodyfat, buddy, that is a lifetime effort for the vast majority of lifters. (For naturals, anyway.)
for 2" on your arms you need about 30-40lbs of overall muscle mass added to your frame - you're saying this will take a lifetime to achieve? certainly not, it can be done in a year to a year and a half depending on genetics and whether the lifter does everything right (which few do).
(note that this rate of progress will dramatically slow down but that's the sort of gains a lifter can expect doing everything right within his first 12-18 months of serious lifting)
my arms went from 15" to 17" in my first year of training and I never touched a drug.. I couldn't even afford creatine (cheap as it was/is) after I bought my food so I didn't even use that. just because you cannot achieve something, don't think it's impossible.
I agree however that it is transformative and will require a MASSIVE amount of effort and dedication from people to actually gain those 30-40lbs (most will simply not eat enough for fear of getting fat - I wasn't worried about getting fat but diligent cardio, carb timing, high protein, nutrient partitioning and some green tea make you a fat burning machine and as a result my waistline stayed exactly the same).
but impossible? if in your mind it is impossible, then you will never achieve it. I visualised a 200kg deadlift by the end of my first year.. and I got that, as well. there are limits to what you can achieve, but if you think it will take you a lifetime to gain 2 inches on your arms, then it will.
just like when people think a 5lb gain in a year is awesome - it is not (unless you're advanced), and unless you've already gained 40-70lbs of muscle mass in your earlier years and you're at an advanced stage, eating the right foods, doing the training and the cardio, being consistent etc for a whole year JUST for 5lbs extra at the end of it and still barely looking as if you train, that's simply a waste of time - consider it a wasted training year. (unless your goal was to gain just 5lbs in which case more power to you

I am talking about people wanting to add significant size to their frame)
