If you race, the answer is easy enough. Is perfect chainline possible? (yes) Whether you need it or not depends upon whether you need to blame some lack or performance on your bike instead of yourself.
for most people, who cares... I mean, if it bothers you, make it perfect so you can move on. If it doesn't bother you it is, literally, 'good enough.'
the answer isn't in the bike.
