Why wouldn't SpaceX be capable of doing life support systems? What's so magically complicated about those compared to the rockets themselves? You have to be aware of the shifting goal posts scenario here. At every stop people said SpaceX wasn't going to be able to do what they were going to do, because there was some kind of magic fairy dust that only government space organizations have. And each time that they achieve a milestone, people just keep shifting the goalposts. They've already done things NASA was never able to do, like build a reusable rocket and land it vertically. Clearly they are more capable than NASA in some ways. Personally, I think SpaceX will be able to do everything they say they will do, up to and including putting people on Mars. They've come this far, why wouldn't they go all the way?
