You are right that this is very expensive. Other firms in this space estimate that there should be a lower bound for direct air capture of $100-200 per ton of CO2 [0].

However, this is a very different product than BECCS - it direct air capture (DAC) of CO2 which would not occur without your purchase, in the only real permanent operating storage facility we currently have. It is very difficult to know what the marginal impact of changes in sugarcane production are, though we do know that there is potential for either indirect land use change, or mitigation of reduction due to shifts in demand/supply and knock-on effects.
