You see a lot of posters commenting that it isn't obvious that it's more expensive, but that's a large part of why I said I'm flabbergasted at how many people don't find it obvious.

It is obvious, someone may still choose to pay it because there's a natural tradeoff, but it's absolutely obvious.

I suspect most developers don't find it obvious because they've never dealt with actual servers themselves.

It's akin to arguing changing the oil on your vehicle is more expensive than paying someone to do it. No, it's more convenient, and that may make it worth the price.
