It won’t be quicker. The laser in the demonstration was cutting through 100 micrometers of steel. Cutting through a chain is going to take much much longer. There are already quicker methods to cut or break bike chains and disable locks. Also cutting with a laser requires very precise alignment with respect to distance. You won’t be free handing this. You’d need to mount it on a device capable of precisely adjusting the distance as you cut deeper into the metal. Plus it’s relatively easy to engineer laser resistant materials.
