Quality software exists and is written by talented engineers. Its written in specific languages and is tested on specific hardware configurations and verifiable. These things cost a bit more. I’m sure if the mass market were willing to bear an enormous cost this would already be solved. Unfortunately I doubt you or your cohorts are willing to pony up $2,999,999 USD a seat (Minimum order 500).
In your fantasy, why does a “seat” cost orders of magnitude more than a first class round trip to Australia in an actual seat? On that note, in the same way that I prefer a more expensive seat on a plane that was designed in accordance with professional and legal standards, yes I’d do the same for software.
Maybe there would even be less cruft and bloatware when externalities were accounted for.
The seat is a reference to a software license. Airlines are economies of scale, this is a small run of software that would meet your expectations to run and be verified to do so. Are you aware how much it costs to develop an airplane? It's more than the cost of a single ticket.
