"it doesn't make sense to target a specific industry"

Normally, we wouldn't want to target one line of business over another because we want the market to figure out where the most value creation is, but it's not always the case.

In this case it makes sense to target people who are literally wasting electricity for supporting a Ponzi scheme. Even if BTC or Crypto is eventually a useful medium of exchange, there's still no reason at all to waste energy in it's proliferation.

Electricity transportation, and to some extent production - is partly socialized in most countries.

The market is not 'all knowing', it's full of asymmetries, we regulate all sorts of things for that reason.
