Simple math unfortunately.

To offset global human CO2 production you'd need to biochar all plant matter several times a year.

This feels like a "yes, and" thing, where the most important use of effort is to reduce production (and we're nowhere close yet), but at some point we'll need to also do capture to deal with production that is truly unavoidable, and, if we're dreaming, to achieve net negative production, for the purpose of returning to preindustrial levels.

But yeah, if you're burning coal with one hand and making charcoal with the other, it's all pretty pointless.

Reducing production is simply impossible.

There's billions of people on earth who are desperately poor compared to even the poorest American.

There is absolutely no chance those people just accept their position as ultra poor.

If individuals want to reduce their CO2 output the only viable strategy is to buy and permanently store fossil fuels.
