There have already been dozens of objective evaluations that support your intuition. You aren't reading about them because of political infighting: a huge number of powerful people have committed themselves publicly to lockdowns as a solution, and are not interested in people learning the truth.

There's a long list of studies here, many of which are all-country statistical analyses:

A representative paper:

"Comparing the trajectory of the epidemic before and after the lockdown, we find no evidence of any discontinuity in the growth rate, doubling time, and reproduction number trends"

etc.
