Banning tips in the hospitality sector would be a bit like banning stock options or similar equity incentives in the tech sector (and startups in particular).
Having to replace such performance/luck based incentives with fixed salaries would make a lot of business unviable, and restrict growth and innovation.
Furthermore, the current workforce in places where such compensation is common will often have self selected for the kind of people who prefer this model (due to the potential upside, excitement, feeling of purpose, etc) over the safety of a fixed salary.
So banning tipping in such markets tend to have a similar reaction as would forcing such incentive models on markets where people are used to a fixed salary.
