If love is a solution to loneliness caused by rising industrialisation, then why does love exist in non-industrial places? Romantic love is a phenomenon that can be found at every point of the globe and is not defined by the habitat we live in. This argument is centered around more economically developed countries because it only considers love to be a consequence of industrialisation in more urban cities. It is therefore biased, and cannot provide an in-depth explanation for love.
Love cannot be a coping mechanism to deal with loneliness because it is fickle by nature. Often, people fall in love with someone inappropriate or unavailable, and as a result, their feelings of loneliness are actually enhanced by love.
If love was a cure for loneliness, then we would never end relationships out of fear of being alone. Instead, we choose to be alone sometimes because we are happier by ourselves.
