I agree with your first four points, but how did you arrive at your fifth point? QR Code applications I've used scan in about 1-2 seconds (the time it takes to auto-focus), which I think is probably faster than typing a URL.

If you include the time it takes the download (or find) a QR Code app, it makes sense. Considering that neither iOS nor Android come stock with a reader.

Agreed, no doubt it takes time to set up a phone to read QR codes. I was more interested to see whether there was some link/study which compared the actually processes of typing vs. scanning, which I thought was the intent of his fifth point.
