LPL's recent videos are quite interesting, but the RFID cards he targets are one the 'low hanging fruit's side of the spectrum: very old systems with no encryption that only transmit an ID. The system he demonstrates harkens back to the 1980s. [1]
There are literally hundreds of other protocols and systems that are much better: the DesFire EV2, etc [2] for similar costs (ie 80c vs 70c) [3][4]
Just wanted to point out that the systems that you hypothesize exist already, and are not orders "Significantly" more expensive.
