It seems like you're implying that there is some negligence or conspiracy. No one could have predicted that United State's Covid response would be so poor. That realization only came about in May when we tried to reopen too early.
Mail was delivering fine 6 months ago. Can you cite any sources that study the infrastructure problems of the USPS?
I for example could easily vote for my invalid parent.
Would you trust someone signing into your server where the only verification was a password you mailed to their house unencrypted?
We definitely have a much higher standard when working with our servers than voting. I mean that from a security standpoint and ease of use.
If the proposed solution is to mail ballots to each registered voter at their last known home address, people who have moved without updating their voter registration may also be an issue.
Given the above, I don't think it is unreasonable to have concerns about this process. That said, perhaps there is an alternative method to proceed if voting in-person is deemed unacceptable.

Previously mail-in ballots were generally limited to specific conditions in order to limit the effectiveness and opportunity of this type of fraud (e.g. coercion and voting for others).
That said and in my opinion it should be left up to the states to decide, but I also think there are better alternatives to limit the spread of covid (e.g. early voting by letter of last name; increased number in general and availability of outdoor polling locations; drive-thru polling locations; ticketing system where they message you when you are next or near next in line). I would also agree with federal grants to states to help fund such initiatives that actually provide a way to limit these types voting fraud that mail-in ballots do not.
