If anything, it's the people on the other side of the discussion who generally think depositing money into banks should be risky because they argue that the government ought to not bail out depositors.
This should be spelled out in law rather than relying on the existing provision being used ad-hoc, though.
In my opinion it's really rather arbitrary at a point. If an individual or corporation has a lot of money that they need to store, they need to consider risk and return regardless. Deposits have FDIC reducing risk, but don't earn much interest. There are government bonds which a different risk and earning profile, and stocks with a different risk profile again.
I feel it's rather narrow to focus only on deposits when in a practical sense it's pretty unlikely that anyone with any meaningful amount of money will keep it all in deposits. Similarly I also have sympathy for small share holders who lost money as part of their pension funds or otherwise. Not sure why hacker news commenters appear so gleeful about these people losing. It's not like bank failures are a "normal" occurrence in any sense.
1. (Main reason) We insure deposits is to keep bank runs from happening. That's why it was done here.
2. Insuring stocks costs more money, and creates far more moral hazard.
3. Most people/companies have far more diversified stock portfolios than deposits.
FDIC is not funded by taxes.

“The FDIC receives no Congressional appropriations - it is funded by premiums that banks and savings associations pay for deposit insurance coverage.“
Should deposits have an associated risk, so that companies prefer to pay their employees in cash and require cash paper bills to settle accounts? If physical cash were required, our economy would be much less efficient.
But it shouldn't. Cash should be riskless no matter where you stash it.
