If you want your investments to be guaranteed by the US governent, that product exists (US Treasury bonds) and it is popular. The yields are pretty low though. People with megabucks to invest who put it in something other than treasuries do that because they chose to accept higher risks in order to chase higher returns. Except surprise, now the risk is socialized.
No, people with deposits in SVB never faced having it all disappear. SVB was insolvent which meant that its liabilities were larger than its assets. That doesn't mean the assets were worthless. The FDIC process is like a bankruptcy. First, everyone gets restored up to the $250K insurance limit. Next, the remaining assets are sold off and the proceeds are divvied up among the uninsured depositors. So the depositors take a haircut: some fraction goes poof and they get back the rest. They don't end up empty handed. Figures like 90% (i.e. they lose 10%) were being thrown around this morning, before the bailout.
