Lockdowns do slow the transmission of the virus. However some lockdowns are more effective than others.
I am an Australian, and I live in a country which has been in lockdown for somewhere around 500 days. While it is difficult to prove what would have happened if the country here did not go into lockdown, I can honestly say that the lockdown here hasn't been highly effective, as there are still 1000s of cases a day and high levels of community transfer. I would say things would have been worse.
I would rather be in lockdown in Australia than here, there are many safety nets in Australia which while life might be difficult in these times prevent what happens like people starving to death. These don't reflect on the effectiveness of the lockdown, but rather the effectiveness of the management of the lockdown.
There is also the mentality of the citizens, lockdowns are less effective when the citizens are less compliant or due to certain government stances. Take one of the areas here, you can travel there and you only have to go into quarantine for 7 days if you are vaccinated, no consideration to the fact that you can still get infected by the virus when you are vaccinated and can still transmit it.
To sum up, are lockdowns effective and the answer is yes if they are done effectively. Do lockdowns impact on personal freedoms, yes they do if they are done effectively or not. Do lockdowns have social and economic impacts, yes they do and so does not having a lockdown.
