We didn't really stop industry. It did show how little effect flying and cruises have (which is good because I like flying) but it also shows that the emissions aren't just coming from luxuries that are easy to live without. Actually shutting down everything one day a week (giving 1/5 to 1/7 theoretical savings) isn't really going to work. Practically a lot of industry can't shut down, or would pollute a lot more by starting and stopping.
