I don't know if I, a frequent Star Citizen player and Day 1 backer would say it lacks "everything", and am unsure if your hyperbole was just for dramatic effect but from the first executable to where we are now in Alpha version 3.4 (soon to be 3.5), we have an impressive amount of content-all things considered, especially via in-game locales and systems that have facilitated some incredible emergent gameplay among the player base.
The "Jumptown Wars" have been an amazing thing to watch and participate in, and I encourage you to go look through the Star Citizen subreddit to see some of the in-game coordination players are engaging in just to secure a static trading depot on a dead moon (diving deeper into the anecdote rabbit hole: I participated in a 12 ship assault on said depot when a pilot in the player "Organization"-SC's guild system-I'm a member of was shot down by a rival group and requested evac).
It's light years from lacking "everything". It's not complete, but it's also not near as empty of an experience as you seem to be suggesting.
