There hasn't been a time when "the individual" handled problems like a war or a massive pandemic. You "as an individual" haven't solved this mess and neither you nor I are going. I mean, I stop and help people broken down by the side of the road, I tell people what I think and what I think needs to be done. But that's individual initiative and it's not going to fix large problems.
Large questions have always been handled by groups, informal groups or formal, either coming from society. When a society was too small scale to produce a large collective response to a problem, well it failed. Why large nations have replaced small tribes.
It's true that today a lot of people view the government as a thing outside of themselves rather than a thing they create. But that's a slightly different problem.
