In theory, I agree with you, but trying to internalize these cost is itself extremely costly. That's why the criticism about econ-101 level reasoning: it's a convincing idea in theory that isn't tractable at all in practice and can only end up with a bureaucratic nightmare.
The EU has many such rules that are designed around economics first principle like that, in order to build an “efficient market”, and they are all extremely burdensome and at the same time ineffective (see EU-ETS, the single Electricity market, CBAM, etc.)
In the realm of policies, tractability is always preferable to theoretical elegance.
