On that point, the government does have an obligation to "provide for the common defense and the general welfare of the United States," and that is clearly one of the overarching purposes of the Constitution itself. I find it hard to argue that saving tens of thousands of jobs[0] but by making the depositors whole, when the assets of SVB, illiquid though they may be, can cover 60-90% of the cost, is at all the wrong thing to do. This is literally part of why we have a government, and why markets are regulated at all.
