I agree that we must do the best we can as packagers. A friend of mine that used to build computers for local folks from his home has a video of a UPS driver kicking an incoming computer box off the end of the truck onto a hard pavement at his house.
As an industrial model maker, I packaged prototype models for the computer industry and learned to pack very well.
We used the six foot rule! Six feet onto a hard cement floor at all corners. We had boxes arrive at the customer that were round with no damage to the model.!
Pack hard foam around everything that can move of the original product and tape it well. there should be no felt movement or rattle at all! There should be no object that is unsecured in the hard packaging. That will prevent dents..the greatest problem. Then those materials should be taped together and surrounded with soft foam and taped. Then the lump should be encased in a box with hard foam and packing materials to prevent movement. Then that box should go into another box with styro bead insulation sheet wrapped in plastic bags to prevent having everything static covered in the little styro peas, Then the spaces should be filled with packed peanuts.
Too much work?? Yup, but it will almost totally guarantee a safe delivery.
just my take on the subject.

I let UPS do all of the packaging to avoid insurance disputes. Just sent my old Cimbali Max Hybrid to a buyer in Canada, where it arrived in fine shape. I had them do the double box "fragile" packing to be sure.

I sold a Hottop.
It shipped to a destination about 470 driving miles from my home.
It was packed in the original carton with all the original packing, just as they would come to your house.
That box was reinforced inside with additional double-thickness corrugated.
The recipient even offered to pay for the damage, whatever it cost, as they said that my packing job was excellent and the damage was not at all my fault.
Fortunately, the purchaser is very mechanically capable and I had a spare base and sent it to them, no charge.

Needless to say, this is the last time I deal with UPS if I have a choice.

I bought a stand-up bass and the "only" way they would ship was greyhound bus .. the seller said too many had been mashed up by the regular shipping companies. My bass arrived safe!
