I wasn't commenting on whether scalability is important or not. I was commenting on that mindset: "When that matters, I won't even be managing the person whose problem that is."

What you said all sounds reasonable. Sure, don't build something scalable if you've figured out you want something quick to prove your market and you're ok with tossing it all away or if you'll never need the scale. These are not the same thing. But this will be somebody else's problem? I don't want that guy on my team... Something someone told me a long time ago, write code like the guy that takes it over from you is a psychopath and has your address.
