I think one of the simplest arguments is that criminals who need privacy will move to their own platforms. Any law that weakens encryption only weakens the privacy of regular citizens.

People make a variant of this argument about guns, but there is an important distinction with encryption: encryption is purely defensive, doesn't escalate situations, and doesn't accidentally (or otherwise) kill anyone.

This framing makes it abundantly clear that any law against encryption is about one thing only: Spying on law abiding citizens.
