Lately I've been thinking, is it really safe that couriers are the ones shipping hardware wallet that we purchased from official hardware wallet companies to our homes?
And who is supposed to do this work? Anonymous, disposable delivery workers whose memories are wiped after every delivery?

Since Bitcoin and crypto are the new gold mine if eventually Bitcoin goes up to $1 million dollars per coin this will make bad actors to even want to commit more crimes just to secure people's Bitcoin.
That is precisely how it will be; after all, look at the surge in crimes targeting crypto holders - it has only been rising in recent years.
My worries is couriers or what are they called have your address and they know what you are buying since the receipt sometimes comes with the item glued to the case or package.
A courier sees only your specific delivery (or a few similar packages), whereas the courier service maintains a database containing such information covering a city, a country, or even multiple countries. The scale here is far greater, and the likelihood of this data being stolen, for instance, by the company's own employees is higher.
My point is that the threat posed by the courier service as a whole may be greater than that posed by an individual courier.
Call me crazy but I am just thinking ahead.
I would call it caution. If you are worried about a local courier, you could travel to a neighboring country and have the order delivered there. However, that wouldn't protect you from a leak of the company's user data, should one occur.
Wouldn't it be better for hardware wallet companies to handle shipping themselves and they will be able to erase data after delivery becomes a success? People who bought hardware wallet shouldn't be known by anybody.
To do this, they would have had to build a different type of business, and it is unclear whether it would have been profitable (even in conjunction with HW manufacturing). Furthermore, this manufacturers themselves are not immune to hacking or the theft of user and delivery data.
