[DiogenesLamp]

Not at all -- the Declaration is all about "necessity"

No it isn't. It does not say "necessity" in the important part. It only uses that word in regards to "a decent respect for the opinions of mankind."

Respecting the opinions of mankind is not a "necessity."

Such has been the patient Sufferance of these Colonies; and such is now the Necessity which constrains them to alter their former Systems of Government.
