We've long known that transmission of COVID through fomites (surfaces) is very low: https://www.cdc.gov/coronavirus/2019-ncov/more/science-and-r...
If this wasn't the case, grocery store protocol would have been very different during the early days of the pandemic.
Cases of COVID-19 spreading through fomites (particles on a surface) are extremely rare[1][2] and COVID-19 has a short lifespan on cardboard[3]. Just leaving deliveries somewhere for a day is probably enough to stop transmission.

> Similarly, on cardboard, no viable SARS-CoV-2 particles could be found after 24 hours, or SARS-CoV-1 after eight.
As viruses can remain active on surfaces, unless you irradiate the deliveries with a UV lamp (and do it again after unboxing them, since there may be viruses on the actual item) even that would not be enough.
> Even if we locked down for 3 months, once we were released someone from another country would come in and re-infect everyone again.
That's if you assume away animals, as viruses that affect mammals are rarely limited to humans (ex: chicken flu)
> Also during lock down do we once again tell the poorest among us that while they are 'essential' that they are also worth less and must continue to work and face the risk alone so as to ensure the rest of us can isolate in safety at home
Agreed. It's time to accept we're not immortals, viruses exist, and yes it's a shame that covid is now endemic, but it's even worse to perform lockdowns of dubious efficiency that only have one guaranteed effect: hurting the economy, and the "poorest among us".
