MPs are stupid then. Which thankfully this article points out. Apple (and I assume Android) already allow for remote bricking/locking of your devices. Apple won't let you disable Find My or other security measures without your passcode and Apple has a way to disable turning off Find My if you aren't home/normal location (so if someone snatches your phone while you are out and they also shoulder-surfed your passcode they still can't disable it).
I have no clue what "strong commercial incentives" these MPs are referring to but I assume it's just general (tech or otherwise) incompetency of elected officials.
I find that vast majority of people, even top people in another field, don’t have a good grasp of what is possible with technology. I don’t say that to make them sound dumb, just they don’t know what they don’t know. You get to be the one who can suggest technologies they can use, either existing things you can glue together and/or custom code to help accomplish a task.
