Though this concept of dismantling the federal government sounds nice, if actually attempted, would take far more than one term.

You are litterally talking about thousands of departments and well over 2 million people directly employed, plus millions of others with indirect employment.

Not to mention, it would require a Constitutional Convention to re-write the Constitution, and therefore State legislature Sign-Off.

Attempting to make even a fraction of these changes in one or two terms would cause massive disruption and devastation to more aspects of governance and the economy than you can begin to imagine.

I'm not against smaller government, but this is a pipe-dream.
To actually dismantle the federal government would take a generation. Plus then the concern would be state governments rising up to fill the void in power, which has its own massive implications.

One cannot simply remove a weight off one side of a scale and expect gravity itself to balance the load.
