The Founders were not for weak government.
They were, however, for limited government.
Big difference, and the two can co-exist. Whatever the fed government is supposed to do (see enumerated powers), it should do well.
But the big difference is that there are only (literally) a FEW things that the federal government was supposed to do.
My may how confused we are today. Today, the fed government is supposed to do everything, but everything in a sloppy, piss poor, inefficient, corrupt way.
Precisely the opposite of what the Founders envisioned.

They wanted something stronger than the “Articles of Confederation” so they took a small step towards that with the constitution and the setup of the separation of powers.
If Newty boy was right about the founders wanting Strong government they would have swung the pendulum to the other side rather than just taking a few steps toward the center from anarchy.
