>Every bit counts. "every bit" also costs political capital. Making any sort of change is going to cause a stir, and if you're going to cause a political shitshow, you might as well get good returns for it. Causing a political shitshow, but only making a modest impact is the worst outcome. Just look at the pasty tax in the UK[1]. The government proposed a change to the VAT rules that would have made a minimal fiscal impact, but generated so much flak that they were forced to back down.

The examples you gave all cause disproportionate harm to a small group, which will raise a stink to their local representative, especially if they're being singled out. An across the board carbon tax avoids both these problems.
