That is quite a stupid argument which you seem to just rephrase without having thought about it, as you could aswell say then that healthy eating takes some more time and consideration than running to the next fast food burger, thus you can only eat healthy if your time is worthless. Or how about developing new energy sources if we can just burn all the oil much easier? Sometimes some efforts have to be done to have nice things. See how dumb this 'Only if your time is worthless' sounds now?
Linux has evolved a lot. Some years ago it was very likely for you to have to recompile the kernel to get your box running... I haven't been in that scenario lately (using Ubuntu).
Then, some distros/desktop environments are even friendlier than Windows itself. elementary OS for instance, is very minimalistic and simple.
So I have to disagree with you.
I properly cash in on my time spent learning Linux when I was younger.
