Would You Sell Your Citizenship?

"America's homeless and panhandlers (who are often different people—some homeless don't panhandle and some panhandlers aren't homeless) are actually quite wealthy. Almost all own an asset—their United States citizenship—that is worth several hundred thousand dollars. The problem is that they are denied the right to sell that asset."

What do you make of that idea, that citizens be allowed to sell their citizenship on the condition they promise to leave the country?
