You don't seem to understand the point of these laws. It is not about stopping anyone with enough technical know-how from encrypting their communications. This is possible today, and not something which can be easily legislated away without resorting to a much heavier class of draconian laws (at which point you won't be living in a democracy any longer in any case).
This is about making it hard (or impossible) for some perceived group of miscreants to communicate privately. People sharing CSAM (however you define that) or dealing drugs, and stuff like that. Anyone can encrypt their communication, but most people don't do this consciously; the masses just use WhatsApp and Signal and what have you.
You and your special keyboard are not of interest, and unless you start selling these along with a service to route the encrypted messages to thousands of users, you are not the target of this legislation. Take away Signal and WhatsApp and sending an end-to-end encrypted message to your drug dealer without exchanging keys and agreeing on a protocol suddenly isn't as easy as just opening an app. That's the point of this law.
It's a dumb law, but you won't make it go away by playing silly semantic games.
