What would happen to businesses if everyone had unlimited cash?

If everyone had unlimited cash then there would be no point of making a profit because everyone has so much money they wouldn't care how much the price is. So all of the business would be a not-for-profit. since every business is not for profit there wouldn't be any competition between any business because everyone has unlimited cash. when  everyone has unlimited money then there no point of opening multiple of different types of business there should only be one main one.
