For me offsetting is the opposite of the Zeno's Paradox. I will emit today an amount X of carbon, so I will pay this company some amount of money so they over some time (years, decades?) will capture that amount of carbon back. The speed of emission is far faster than the one of capturing back, even if we assume that all emitters somewhat offsetting them (that is not true, specially for the worst offenders). And if we had millions of years left that wouldn't be so severe, but we don't. Already a lot of positive feedback loops are triggered so the natural world is having its own share of emissions, and they don't buy carbon credits. The other reason offsetting is wrong (at least for most used capture methods) is that they aren't taking out carbon from the carbon cycle. If you plant a tree, it still is in the carbon cycle, while the carbon that I'm emitting have high odds of coming from carbon that wasn't in the cycle (buried oil, coal or natural gas that were out for millions of years).
