Our current technology is capable of doing everything you listed and more. The problem is their cost. There is no point to doing it while the cost is this great and there is absolutely no monetary return from doing it. And Musk's effort has been for reducing that cost so that he could do it with the capital he has.
If need be, large countries that have the technology like China, Russia, US could do it. But it would still require gigantic amounts of capital allocation and effort at this stage. So no one will do it. The biggest thing that is happening right now is China and Russia signing an agreement to build a base on the moon. (yes)
