It is absolutely essential that we keep our minds open to alternative explanations for the universe in which we live and with which we interact. Just because one explanation is the accepted explanation doesn't mean it is "right" - there may not even be a truly "right" answer to a lot of the deep, probing questions about the universe. If we hew too strongly to a single explanation simply because it is the one that is commonly accepted, then we will inevitably be scoffed at by our ancestors the same way we scoff so readily at those who did not accept Copernicus's teachings.
When I say that space has an image problem, I mean that the common conceptions of space are distorted. The typical person not only doesn't understand space, they don't understand what we do in space. That matters, because ordinary people interact with space technology on a daily, sometimes hourly basis. I don't just mean people like me, who work in the space industry. If you own a cell phone, or use a credit card, you are almost certainly interacting with space technology when you use those devices.
