What matters is whether the revenue from plastic bag sales actually goes into the cleanup effort, offsetting the externalities. If it doesn't, then the whole policy is a sham. If it does but the revenue is not enough, the price tag should increase until it accurately reflects the true cost. Increasing the cost to well above pocket change might have the welcome side effect of making people care more, but IMO that's a secondary concern.
