Okay, but from my understanding, in order to change galaxies, I have to find a portal, figure however to use the portal, and then switch galaxies.
As soon as you can use the space anomaly (which happens very early) you already have a possibility.
But apart from that, sure, it still takes a bit of effort and is not an option available when starting the game. The latter would be a nice idea though.
I didn’t know about portals or even that switching galaxies was even a thing. […] How am I suppose to know that after going through 6 more galaxies that I can get what I wanted from the start?

But I get what you mean as this is not clearly communicated right from the beginning in the game and something to be discovered. So your best chance to know this, besides doing the story missions, is to talk to other players or by curiously clicking on some suitable links in the NMS wiki.
