To me the word “should” implies a need and opportunity for making a moral choice.
This article about the American IRS trying to penetrate the (completely irregulated – by design!) Bitcoin economy (if you can call what is happening around Bitcoin an economy). The last paragraph in the article uses the word “should”:
“The FinCEN [Financial Crimes Enforcement Network] rules say Bitcoin exchanges and Bitcoin miners should register as Money Services Businesses”
The nature and purpose of Bitcoin was to create an ungoverned (and maybe an even ungovernable!) currency. Its current “Boom & (ultimately) Bust” cycle was fueled by a systemic failure of existing economic systems – specifically the recent financial events in Cyprus in which money was essentially confiscated from private bank accounts. The IRS is a part of this failing economic system.
Therefore the IRS has no moral ground to stand on. So I am assuming that when it says “should” it is reaching for legal ground. But we’ve drifted very far from that island to. Which means that the word “should” has become an empty shell … and the IRS is in no position to fill it.
