No, it's not possible to do most of the things you listed purely online without physical, in-person communication. Silicon Valley still hires engineers and drags them into their physical office in San Francisco, instead of hiring them remotely, because you can't even build a software company fully remotely, forget about a physical world factory or chemical plant. Even the so-called fully remote companies were built on a lot of in-person collaboration between a small founding team in the beginning.
