It is well-known that RSA needs much longer keys to achieve the same crypto strength. Ethereum uses ECC, and I was talking about ECC, so it is not clear why RSA is relevant here (or ROT13, for that matter).

It's relevant coz Vitalik wants Ethereum to be universal. Also ur position that 256 bits is enough reminds me the myth about Bill Gates and 640K.

you asked for 32-bit key because it would be "convenient for java and javascript guys". this is the opposite of "wanting to be universal". obviously, you are not familiar with cryptography at all, otherwise you would know which key sizes are considered secure. also, you would not compare RSA key length with ECC. it would be interesting to observe whether your arrogance will overwhelm common sense and you continue to argue.

256 bits will be enough for quite a long time, unless quantum computers appear (actual ones, not dwave-type), in which case 512 will be as useless as 256.
