In theory what you are describing is a more efficient economy which would actually boost the economy, except for those unnecessary producers. Everyone cuts out unnecessary items and has more money to spend on necessary items. This is kind of true as the supply of nearly everything can’t meet the demand at the moment. Less people cutting hair and washing clothes means more people can work on producing other things people want… however since things that people want are mostly produced in China we can’t properly reallocate the labor force to increase production to meet demand, in particular in cities. US is way behind on manufacturing and is completely missing the tools to ramp up production. We are missing entire business to business categories that make production impossible because no one knows where or how to obtain raw materials or supplies, let alone the machinery to produce goods.
