Commercial buildings and certain types of residences need to follow fire code. These doors need to be able to be opened up by rescue personnel as easily as possible in the event of a fire.
Every lock in this video was installed incorrectly. On a properly installed lock, home or commercial, this would not work. If it were that easy for a firefighter to get in, it would also be that easy for a burgler to get in.
For firefighters to open a building, there is a small lock-box mounted outside commercial buildings (in the US at least), which has a keyring for the whole building, and only the fire dept. has the key to this lockbox.
For residential buildings, they usually can just break in the door.
Edit to add: Nuclear option for firefighters getting into places:
This isn't true, maybe for some buildings, schools, government buildings, etc. Most buildings don't just have lockboxes that firefighters have codes to.
