The IETF believes that adding a requirement for wiretapping will make affected protocol designs considerably more complex. Experience has shown that complexity almost inevitably jeopardizes the security of communications even when it is not being tapped by any legal means; there are also obvious risks raised by having to protect the access to the wiretap. This is in conflict with the goal of freedom from security loopholes.
You don’t need technical knowledge to see the problem.
If you live in an apartment and your landlord has a master key, then all an attacker needs to do is get that master key. In an apartment complex, maybe that’s okay because who’s going to break in to the landlord’s office? But on the internet, tons of people are trying to break in every day, and eventually someone will get the key.
Even for the landlord, I’d rather them have a copy of my key than a master key, because that way they’d need to steal my key specifically.
From RFC 2804:
https://datatracker.ietf.org/doc/rfc2804/
This was written in 2000 in response to US government requests to add backdoors to voice-over-IP (VoIP) standards.
It was recognized 25 years ago that having tapping capabilities is fundamentally insecure.

And I had one experience where our landlords attempted to rob us.
