"For those who would pick SPECKS, would you pay a single penny to avoid the dust specks?"

To avoid *all* the dust specks, yeah, I'd pay a penny and more. Not a penny per speck, though ;)

The reason is to avoid having to deal with the "unintended consequences" of being responsible for that very very small change over such a large number of people. It's bound to have some significant indirect consequences, both positive and negative, on the far edges of the bell curve... the net impact could be negative, and a penny is little to pay to avoid responsibility for that possibility.
