You do not have linear costs of removal. Just letting nature be has no additional costs, but in the amount necessary extreme opportunity costs.
Technical systems might have a theoretical cost, but practically any energy put into removing CO2 from the atmosphere is much better put into not using fossil fuels to produce energy for a different purpose.
Meanwhile the cost estimates for the damages incurred are in regions of 200-500 €/tonne now. So unless we also properly tax imports and other countries also do carbon taxing, it will be the death to any industry.
An increasing carbon tax is an important instrument, but it can only be part of many measures, most importantly ramping up the renewable production by all means.
