This is a muddled statement. It is a stupid reason to "execute" the act of silently modifying your host file.

If I murder somebody to keep them from stepping on my foot, and the judge says that it's a stupid reason to murder somebody, it's silly to say that the reason is "OK" because it hurts to have one's foot stepped on.
