I think a better argument against CDR is that it's so slow to act that you probably wouldn't want to pull down the temperature once it's been high for so long.
Would we really want to go right back to pre industrial temperatures today? If not, why should we assume that future generations will want to go back to today's climate? Why will they want to go back at all? Prevention of rises is preferable to facilitating falls. CDR can't do that, in practice.
