Last week the Greek bailout ballooned into a gargantuan 750 billion euro (nearly $1 trillion) debt stabilization fund, including a $39 billion line of credit from the International Monetary Fund. This coincided with the European Central Bank (ECB) announcement that it would immediately begin purchasing junk-rated Greek debt.

It won't work. The problem isn't liquidity, psychology or speculators. Germany and France simply cannot borrow or tax enough to cover Europe's debts and looming deficits. So, barring a fiscal and growth miracle, we will either see sovereign defaults (larger and more chaotic for having been postponed) or the ECB will have to print euros to buy worthless debt, leading to widespread inflation. Since inflation lowers the value of promises to state workers and pensioners, and also is easy to blame on others, it will be an especially tempting escape.

Notice who is missing: Greek bondholders are not being asked to miss a single interest payment, reschedule a cent of debt, suffer any write-down, take a forced rollover or conversion of short to long-term debt, or any of the other messy ways insolvent sovereigns deal with empty coffers. Those who bought credit default swaps lose once again.

But why? The reasoning behind the Greek bailout is founded on several myths that need exploding:

• Saving the euro. We're told a Greek default would imperil the euro. The opposite is true. Allowing Greece to default, or to renegotiate with bondholders, would be the best way to save the euro. A currency union is strongest without fiscal union. Then countries are no different from companies. If they borrow and cannot pay back, investors lose money. The currency is unaffected.
