Realistically carbon removal will only happen after we removed most carbon emission sources. Carbon removal will likely be more expensive than reducing emissions for decades to come. This is a future technology for the time, for the "fuck, we already produced far too much emissions, what do we do now?"

This is of course only profitable within an emissions tax/trade framework, and hopefully those will extend to the factories causing emissions and thus enabling them to take part (by avoiding the tax imposed on their products by responsible countries).

Nevertheless, that can only decrease the addition of CO2, while this can potentially reduce the absolute amount in due course.

It isn't profitable because these cost of CO₂ generation is just externalized to nature.
