By restricting lawmaking powers of future Congresses, PPACA thus attempts to amend the Constitution by statute

An obvious impossibility.

Suppose Obamacare goes into effect (that can't happen, because that's not its purpose). Further, suppose it works as planned.

Then, in 2036, a Congress passes a law, which is signed by the President, dissolving IPAB.

It is inconceivable that IPAB could continue. There would be no basis to overrule such a law.

"it is therefore tempting to dismiss IPAB as an absurdity that the body politic will soon reject. Until that occurs, IPAB will potentially empower just one unelected government official to impose any tax or regulation, to appropriate funds, and to wield other lawmaking powers."

We will see when it is rejected and removed. Until that time it is "the law of the land".
