I disagree with you quite strongly on this (and I don't believe there really is enough of a dialog to 'rashly reject'), however, if plants do indeed 'feel pain', so what? Humans can live off fallen-fruit and seeds, but the acreage required would prohibit human populations above hunter-gatherer densities, and in almost all areas of the planet this method of eating would produce severe malnutrition.
