I think the 0 luggage is a bit more dubious of an idea.
Firstly, some people decide to fly at the last minute. So the "pack ahead of time" is problematic if you aren't planing ahead.
What might be in the luggage? A laptop. Cloths. Toothbrush. Miscellaneous personal items. These are items that people use frequently, and may not have a spare of. "I'm going on a flight next week, so I need a second toothbrush, one to pack and one to use until then". That is the sort of inconvenience that adds up across many small items.
Then the luggage needs to be delivered. So you need to deliver it to an airport, and have the some airport baggage collection mess. (Or you could have it delivered to your destination, and get a whole lot of new problems)
You would need to take the extra bag into the nearest post office at least.
If your travel plans are more complicated, say with 4 flights spread over 2 weeks, then your going to end up with several bags being delivered to several places in a confusing mess of logistics. And if you change your plans, and now the bag being delivered from A to B needs to end up at C, then woe betide you.
