I also think it's appropriate and normal to use both deontological and consequentialist ethics.

I never got much into Natural Rights Theory though.

I like what I've heard from the philosopher Michael Huemer.

He argues from an intuitionism perspective.

Basically arguing that we intuitively know that our life is our own without using much if any philosophical framing.

And that it doesn't seem to make any sense that the government should have any special authority over us unless it serves a very good reason.

The approach is clean, to the point, and cuts out any framing that's starting point based on an intuition anyway.
