I think this song is a metaphor for life on the road while touring as a musician. The men go out and the wives and families are left behind left to worry about what will be returning and when. It seems to defend the lifestyle, admitting that it is crazy and unorthodox, but also the only way to reap the rewards of life as a musician. If we never "dropped out nets", we'd have nothing to show for it.
