This vaguely reminds me of the fact that in many countries, pure ethanol sold for industrial purposes is intentionally made poisonous, so you can’t drink it and thus merchants don’t have to charge the taxes on it that they would for spirits.
It's more like "so you can't drink it" without the taxes part. Those taxes play important role in reducing alcohol consumption (though they are of course not the only tool), so making cheap ethanol poisonous and with different color closes the loophole in healthcare policy rather than opens a loophole in taxation.
