There’s layers of nuance to such a seemingly simple question. Specifically when you ask “all that”.
Did we need the initial 21-day lockdown? Absolutely yes.
Did it end up being necessary to extend the lockdown because it turns out our country no longer has the resources or expertise to rapidly ramp up testing and intensive care facilities? Also yes.
Did we need to ban cigarette sales for so long? No!
Did we need to ban alcohol sales for so long? No!
There were several middle grounds / compromises that were completely untested during this whole debacle.
Could we have temporarily raised the “sin taxes” significantly rather than completely ban sales? One academic paper says yes.
Should government have unbanned cigarettes with alcohol? Absolutely yes. The continued ban of cigarette sales just made no sense whatsoever.
Could government have allowed restaurants to serve alcohol while sales were banned for home consumption? Possibly. Unfortunately there are establishments that would take the piss, but it would arguably have been useful to at least test this for two weeks.
