It would seem not.
Because 1 + 2 + 3 + 4 + 5 + 6 + ... = 1/12

I'm not sure if making a comparison like the above is valid. Perhaps I misunderstand comparisons of infinite sequences?

Of course, the series as written do not converge, so simply taken at face value the question is nonsense.
One can
assign values to the sums by misusing formulas. The value 1/12 assigned to 1 + 2 + 3 + ... is a case in point. We have
The zeta function is defined at s = 0 and at s = 1 (though is
not given by the above series at those points), taking the values 1/2 and 1/12, respectively.
Cheerfully disregarding the invalidity of the formula, mindlessly plugging in s = 0 gives
1 + 1 + 1 + ... ad infinitum = 1/2
and plugging s = 1 into the formula gives
1 + 2 + 3 + 4 + 5 + 6 + ... ad infinitum = 1/12.
And 1/2 < 1/12.
