Absolutely - I know that but thanks for pointing that out again. There is no real "use case" for NOT storing the key into a root owned file. However, as I don't do it for myself there is no way of accidentally deleting the file, copying it quickly from my system to another drive when I accidentally left a root shell open and went to the restrooms (that never happens;) and the one single place I store the key (my head) is pretty much unreadable for everyone except me (at least for now :-) Being paranoid doesn't mean they are not after you :p

Since I reboot my notebook only about once in a month it is no real hassle to enter the key twice 12 times a year :-)
