> First, none of us have any power to "tax it more" so this is a dead end of discussion.

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).

> 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).

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.
