I don’t think the government being inefficient is good. It gives ammo to those who are ideologically opposed to government doing things. We should strive to improve government efficiency, especially those of us who think the government should be taking on more tasks.

Ideological opposition to extensive government is because government is inefficient. See the Laffer Curve. Actual demonstrated inefficiency is the proof, not the justification.

You see the moral hazard of electing people to run government who have a vested interest in being proven right about government being inefficient, don’t you?

I am fine with people who are realistic about government being inefficient, but I insist that they nonetheless try their very best to improve that efficiency (fully considered efficiency, not just making life worse for government workers or people seeking government services). The problem is when you elect people who have an interest in making sure the government is inefficient because then they can use that as justification to enact their ideological goals of cutting government services.

Laffer Curve, really? The inefficiency is neither proof nor justification, it's a side-effect of fairness.

It’s not. For a constant level of fairness, there’s a wide array of efficiency.

What relevance does a economic theory about taxation and gdp growth have here?

I'm guessing the inefficiency-is-good formulation was chosen for rhetorical effect rather than because OP believes inefficiency is good in itself.

Sure yeah, but to be sure, inefficiency is a side effect of the complexity.
