Encryption backdoors is not a case of extending reach for a government, but an effort to get the capabilities back.
They were able to do that before. They just want to be able to continue now.
Note: No, I don't support the idea of backdoors. On the contrary.
The reason is that they have been trying again and again to do this in various forms, slightly modifying tactics so any opposition to it has to start from scratch.

If you wanted to make the corresponsing strong argument for Chat Control and its ilk, the EU just wants (the juicy part of) what the US already has. The remote root level control of most end user devices is not under EU juristiction. So they naturally want companies operating in the EU to give them one piece of access to the presentation layer, too.
This argument is what one must be prepared for, the encryption itself is less relevant..
