Are the markets too big to fail?

Saw a comment today about how the strait closure is kind like COVID that we won't see the full effect until the disease is literally in our face hence why markets are holding up so well. This got me thinking about if the market is too big to fail. COVID was a historical disruption in supply chains and just the everyday lives of everyone. It grinded daily interactions to a halt (unless its online or outside). Yet the government was able to do things to instantly lift the markets back up and to all time highs. Are we too big to fail? Just about everyone's pension depends on the market going up forever, insurance companies, banks, endowments, even charitable foundations are deeply invested in markets. There seems to be a bottom in place that as we drop X% the government will step in. This weekend we have seen an escalation in the war as both sides attacked commercial shipping yet here we are the entire drop in futures have been recovered
