Actually it's better if I'm more straightforward here: it was suggested that since individuals pay the cost of the lightbulbs, they should be allowed to make the choice to buy them or not. They pay the cost of production and transport, of retailing, of replacement, and particularly of the extra energy that they use during their lifetimes. Why shouldn't the person who is paying the cost be able to make the decision of whether it's worth that cost or not?
In response to this it was pointed out that some of the costs of incandescent bulbs are not payed by the user, but are spread out to society in general. These externalities cannot be included in the price of purchase. Global warming is an example of such a cost, I suppose others like energy security, blackouts, etc. might be other possible such externalities.
In response to this you point out that you pay extra taxes when you use more electricity. I replied to that that those taxes don't pay for the externalities because by definition we don't know what the extent of those costs to society is. You reply that because we don't know what those costs are... well, somehow it seems you think that since we don't know what they are, they aren't important.
But that's the point, as a society we seem to have found those costs to be, A. meaningful and B. not worth paying. So we prohibit the sale of incandescent bulbs because their benefit to society at large is not worth the cost.
Is there a discussion worth having about whether or not that's a reasonable conclusion? Certainly. But to have that discussion it seems disingenous to suggest that those costs somehow don't exist simply because we can't completely quantify them.
