A few points in response.
- No fan of lockdowns. My at-the-time assessment was the March 2020 lockdowns in the US were likely 80% unnecessary and 20% might have been helpful. I held that opinion through March-April. My mid-May, the evidence of the of the earlier Nov-Dec. 2019 introduction of COVID became known in the technical community, which bolstered the case for earlier US lockdowns. My opinion evolved to be less hateful of lockdowns based on that evidence, as it kept the New York/New Jersey mortalities from spreading US wide in the Spring.
- As for success of lockdowns, it is mixed. There are some fairly high success examples in Australia, New Zealand and Hawa'ii. Note those were all effectively islands and mitigated by aggressive screening/eradication inside their bubble. The next tier of lockdown success is Singapore, South Korea, Germany and the Scandinavian countries (except Sweden); they all have taken some early economic hits but have suffered relatively minor mortalities and limited economic loss. They also were all democracies, albeit more homogenous and compact than the US.
- Sweden's attempt for community-wide immunity is a massive fail. Sweden has suffered outsize death rates and is now severely lagging in economic performance compared to its neighbors, all of whom share similar genetics and political systems but did use lockdowns. A year into a pandemic, Sweden looks stupid, especially since Norway will see a predicted 3.7% GDP growth compared to -6.9% in Sweden during CY2020.

- Lockdowns absolutely defer COVID case growth, to the title of the thread, they don't necessarily stop future cases unless a prophylactic solution such as vaccine is available. The Swedish case makes a compelling case for conserving economic activity by cooling through lockdowns versus laisse faire approach.
The US CDC published their cross-sectional Delaware lockdown case study, which found lockdowns contributed to "an 82% reduction in COVID-19 incidence, 88% reduction in hospitalizations, and 100% reduction in mortality in Delaware during late April–June."

You may not like the reductions in freedom or the terrible economic consequences, but there is strong evidence indicating there is longer-term value.
