If the solution is not to cut excessive and unchecked spending, you tell us your solution for the dealing with the problem?
> remove whole departments (remove all of the education, veterans, and defence, that will net you 1.5T)
AFAIK DOGE or rather Elon hasn't specified how they are going to cut $2T from the annual budget so all this is speculation and we don't actually know which sectors might receive the cuts. For all we know it could be a goal setting figure. Even if they don't reach this target, the endeavour is still worthwhile. They have 4 years to sell their plans to Congress after all.
In summary you fail to make a good case for why DOGE is a bad idea other than Elon bad. I challenge you to remove this bias from your thinking, it alone just may help you avoid missing the forest for the trees on the issue of government overspend and the relation to uncontrollable public debt.
