The issue is that space launch is a lot smaller market than EVs with a lot higher unit costs. I think the majority of the companies you mention are going to fail, because the market isn’t big enough for them all. Rocket Lab is most likely to survive because they’ve already got a decent sized business even though it is primarily at the low end, but moving up the market is arguably easier than starting from scratch. The others are competing not just against SpaceX, but also Blue Origin (which despite being rather slow is still way ahead of most of the companies you mention), as well as against Rocket Lab and each other
