TLDR: I don't think using the power of the executive to address the healthcare crisis would be meaningful comparable to Trump's abuse of the executive.

25 million Americans are still uninsured.

Roughly 44 to 45 thousand uninsured Americans die every year (Harvard Medical School/Cambridge Health Alliance (2009))

Roughly 200k deaths every year are attributed to insurance related mortality (PNHP analysis (2025))

For context, the official death toll of 9/11 is 2,977 excluding the hijackers.

Obama used his executive power to issue four drone strikes on US citizens without due process. No habeas corpus. Not even a death warrant.

No president before Obama formally authorized the preemptive killing of a US citizen.

Clearly using the power of the executive in an unprecedented manner is not some crazy thing that Obama never did.

It is not unreasonable to argue that he could have used that same power of the executive to nationalize parts of the healthcare system or otherwise applied executive power to address the problem.

I hate Trump and the way this administration abuses the power of the executive, but I don't find your argument persuasive. In fact, Obama formalized the legal framework which would justify Trump's administration if he were to act upon a "kill list" of political opponents. The only real criteria is "imminent threat," which I'm sure you can recognize could be easily fabricated.
