I am not sure how best to interpret all of this... Basically every line is referring to an absolute requirement finally leading to the line that says "How can there be youth without love". However, when the first line asks "How can there be a winter without snow" (something to that effect) or the line like "How can there be an art that is not beautiful", one can argue all of these are possible...However, the line about women and want/like has no exception...
So, may be Kannadasan is using all of these to say, for the most part all of this is true, but there are indeed exceptions to all these rules; so, there may be exception to the question "How can there be youth without love"...
