Highlighting the SpaceX data points would definitely help with readability. But origin at zero is a good thing; charts with Y axes offset from 0 are generally worse than worthless - they're actively misleading (and often purposefully so).
I don't get the automatic dismissal of graphs with offset axes.
Yes, this one is better because it starts from 0, but there are plenty of reasons to offset a graph. For example, when you want to look at curves correlation (you may even want more than one offset at the same time), or study the change behavior.
