There's no way that all 50 States would have united as independent Nation-States.
There's no way that we'd have our current level of social freedoms with States imposing their will on the Federal government.
We need a strong National government to guarantee the Rights of the Constitution to all of us.
The Articles of Confederation failed because the States had too much independence. The Civil War happened because States wanted to be independent from the National government.
America, as we know it, simply wouldn't be a thing if the National government wasn't strong enough to tamp down the insurrection from the South and impose its will on the States to actually live up to the words of the Constitution and its Amendments.

What on earth are you talking about???
The drivers behind both the Declaration and later the Constitution were Southerners, including
Rutledge, Hall, Lee, Jefferson, Madison, among dozens.
Their political impulses supported states rights, rejecting centralized government which was their heritage from the English Whigs who supported a constitutional Monarchy, opposing absolute rule. Recall the Colonies were ruled by Great Britain for some 200 years prior to our independence
The South, governed by the Agrarian and Rural Democrats, supported States Rights, decentralized government a well as free trade; which constituted our governing philosophy prior to the Civil War.
The North, following the Civil War, was governed by the Republican Party who supported trade protectionism and centralized government, encouraging judicial activism; their governing philosophy.
They were and remain the errand boys for the Mercantile Class which later morphed into our crony capitalist posse on daily display in DC.
