At first glance, the CO2 lagging temperature would mean that it?s the temperature that controls CO2 and not vice versa."

Nobody is claiming that CO2 "controls" temperature. Rather, it's being said that, along with other greenhouse gases, it
influences it, and that human CO2 emissions are proving to be a strong influence on it.
Aside from that, it is indeed generally accepted that CO2 lags temperature in Antarctic graphs - but not by very much. It is generally believed that in the past, CO2 and other greenhouse gases worked as a feedback mechanism - higher temperatures caused the release of more CO2, which amplified the rise of temperatures. Later on, the earth cooled again due to other factors than CO2, though fairly slowly because of the presence of additional greenhouse gases.
The idea behind AGW is not that CO2 is the one and only factor influencing climate. If it was, it would indeed be a ridiculous, palpably false theory.
Instead, the theory is that it is one of many influences on natural climate cycles. By releasing shitloads of greenhouse gases into the air artificially, however, humans amplify this one specific factor significantly.
Of course, that does not imply that other factors have suddenly become non-existent, but rather that human influence is having an acute and measurable effect on the dynamic balance, which may cause effects severe enough to have a large negative impact on the well-being of numerous people.
