I'm not, from the same email you are quoting incomplete:

"13 rAnd0.m_C?arS are probably less secure, than 13 random words,
because even an illiterate human knows more words, than we have got keys
on a keyboard. This is indeed speaking pro Diceware :)."

So I agree, that Diceware seems to be the best method without using
special hardware.

The comment of my follow-up email, is just a joke:

"OTOH if I should talk in my sleep, it would be easier for my fraudulant
girlfriend Mata Hari to catch words, than the (not enough, to modern
security standards) random chars I'm using at the moment."
