You’re nitpicking unnecessarily. OP meant it’s a tax on the efficiency of the broader economy directed into private pockets. The word tax is not limited to fees imposed by the government. On the other hand even if limited to government fees, OP still described it accurately because it’s a tax levied by members of the government essentially in their official capacity but illegally and directed into private coffers.
