All those reasons (other than being a member of the Dow - that means nothing on a go-forward basis and it wouldn't shock me if they were removed from the Dow at some point) I think are good ones that the company won't be allowed to go bankrupt, not necessarily that the stock is a buy. The company will survive, but that doesn't mean the equity will be valuable.
You've got the CEO out this morning talking about how the entire aircraft industry might have to restructure itself given potential changes in the types of planes airlines want in a post-virus world. Likely 7+ years until global passenger traffic gets back to 2019 levels. That backlog they had before COVID-19 has probably evaporated. Really long road ahead. The stock is going to stop going down at some point, but that doesn't necessarily mean it's a good one to allocate capital to in a market full of other options.
BA went from being a trusted company because they built quality aircraft that were better designed than Airbus to another sleazy US corporation. Frequent flyers(business) typically would look for Boeing metal to book a flight.
They had engineers in charge for years, but felt they needed to make more profit so we got cost Cutting and untruths.
They are not in an industry where quality and safety should play 2nd fiddle.
