Here’s a narrow critique, you don’t understand that limiting campaigning privileges name recognition which is something only existing officials or celebrities will have.

In a representative system where you vote directly for candidates and not parties like in the US you need to know who is who and what they support.

Banning campaigning hurts challengers to the status quo.

I could keep picking your naive suggestion apart but this is I believe sufficient evidence that you haven’t done your homework.

Start with the fact that it's impossible and will only benefit the candidate that best bends the rule or is able to blatantly break it without repercussions.
