> RSA 2048 keys are unbreakable for the foreseeable future, and using 4096 bit keys are just being paranoid with no gain

This is only true if you consider pure brute force as the only way to "break" RSA 2048. While as of right now there is no hard evidence there has been plenty of hearsay that some of the 5 Eyes have had tools for years that can drastically reduce the brute force complexity needed for RSA 2048 keys.

There is also really no such thing as being "paranoid with no gain" when it comes to computational security, since digital assets can be stored indefinitely and compromised in the future with more advanced computational power or techniques. On the contrary, given the computational power of your average laptop/server these days there's really no reason to _not_ use 4096 keys, unless you are operating on FAANG scale.
