In a capitalist system, no matter if the monopoly is state, corporate or private, perennial crises are a feature, not a bug. (In a communist system, constant crisis is a feature.) In a free market system where the actors voluntarily do not strive to create and control monopolies, and also voluntarily differentiates between earning a living with a little extra to set aside for the future, and maximising immediate monetary profit at the expense of all else (aka capitalism: freemarket economy made into ideology), your suggestions might work. Now then, what are the odds you think of all actors voluntarily working to ensure that said free market doesnot evolve into private monopolies, company towns, indentured servitude where you're paid in company script, total devastation and despoiling of resources, and so on? About the same odds of communism working as claimed, I'd argue. You need something more.
