I don't think it's smart to just cherry pick the design constraints you feel don't apply to you, and proceed to argue others should also ignore them.

Just because you are ok to let your pet project crash and be out for long periods of time, why do you assume it's ok for everyone to do the same?

Think about it for a second: what would be the impact of a storefront to crash during a black Friday type event? Do you think people don't get fired for dropping the ball in these circumstances? Heck, you have papers that document how a few extra milliseconds of latency in a store page is correlated to measurable drops in revenue, and here you are claiming that having businesses crash is no biggie.
