I've made the argument before and the people who disagree with me were neither convinced, nor able to present convincing reasoning/evidence themselves, so I'm not really keen on making it again.
Don't think in terms of buy-ins, but in dollars or BB. Deeper stacked we are playing bigger pots more often because we have more dollars. Shorter stacked we are getting all-in much more often, but for smaller amounts.
Variance has a formal definition which can be used to show an upper bound as a function of stack size. Another way to think about the problem is by looking at extremes. Would a 1BB stack player have higher variance than a 1000BB stack player? Obviously not as the size of pots the 1BB player can play is extremely limited. Even if he goes all-in blind every hand he will have pretty low variance.
The problem with this discussion is that variance has a colloquial meaning that contradicts with the formal definition. For most people variance is ill-defined which allows many different beliefs to arise in conflict with the formal definition. It would be best if every poker player just studied entry level statistics, but I don't have high hopes.
A final note is that there are two variables that are important to consider when comparing strategies. People often talk of variance but ignore win-rate. If variance is decreased, but win-rate is decreased as well, it may be less likely for a player to win over the same period of time and they may require larger bankroll requirements despite lower variance. I believe this is the case for typical short-stacking strategies where rake is huge in small pots, but I think short-stacking probably has lower bankroll requirements than full-stacking in a rakeless environment. I can't prove this though.
