What do you mean by ‘existing’? You obviously don’t think anyone’s calling for the abolition of soap. Is it really puzzling to you that someone who favours the abolition of capitalism as a whole favours eliminating profit-maximisation from [insert economic activity]?
The line of questioning is a little spurious in any case. Factors behind the things on your list are involved in the irreplaceable provision of a good or service. If we want produce, we must have farmers. If we want groceries, we must have a system of distribution and a point of acquisition. Ditto soap, vitamins(?), medicines etc. No-one could say with a straight face “If we want housing, we must have landlords”. Landlords are not, not even arguably, necessary for the existence of housing in the way that farmers are for the existence of agriculture.
