First, none of us have any power to "tax it more" so this is a dead end of discussion. Second, people have agency and we can hold them accountable socially for negative actions even if they are abiding by the current laws (or tax regime). This happens all the time, because laws don't fully align with morality in a culture. Suggesting that we should leave such things to the sole discretion of the economy and taxes describes a strange unhuman-like society that we don't live in.

Well, the choice is: either we leave it to economy and taxes which work, or we'll rely on shaming which doesn't work. To put it another way - it depends if you want to actually fix the problem or just want to have a moral high ground and don't really care about solving the problem.

You probably have more power over that than changing a whole population's behavior.

I'd wager you probably have more power over that than changing just one person's behavior (Felix).

And people are holding you accountable for the shaming. This leads primarily to polarization, not change. Polarized folks are more likely to increase the negative behavior.
