That's a really clever analogy, but is it really a trick? UberEats delivers the food to my door but if I go to Costco I have to make my dinner myself. Sometimes life happens and UberEats isn't just a convenience thing, it's the only way I'll manage to feed me and my crew. I could run a pubsub queuing system and a database myself, but if I don't have to do that, it frees me up to focus on the tasks I'm really trying to accomplish instead.
That's fine, but I think it is a bit reckless to tell everybody that grocery shopping is useless and we might as well order from Uber Eats three times a day.
Which is basically what happens with everyone terribly afraid of managing VPS that these days it's only AWS, Azure and GCP. First the excuse is "it's too small to bother doing it myself", then it becomes "it's too large to run it ourselves".
Some can afford 3x daily Uber Eats, but we should stop discouraging home cooking. It is not that scary.
