Nothing is stopping people from saving (I mean, except for low real wages), even with inflation, it's incredibly easy nowadays to put money into investments. Also I don't understand how deflation would eliminate the boom/busy cycles

Sure, but cash is lower risk. While overall investments tend to do well, I've seen many do awful. Some are legitimate investments that just go bad, while others are scams. People are not as good at telling scams from legitimate investments as they like to think they are. If there was no inflation at all just keeping your money for a rainy day in your mattress (any place a thief is unlikely to look) would be good advice, but cash loses 2% every year so it isn't.
