Yes, one of the core things that Starbucks (and McDonald's and so forth) sells is consistency. Their products may not be great, but you can go to one anywhere and know exactly what you're going to get.

Mom-and-pop places don't have that certainty. There are both great and terrible ones.

If you're in an unfamiliar place and just want a coffee, Starbucks can be just the ticket. It's not a gamble. And if you enjoy coffee and want something above "adequate", you'll also be keeping an eye out for promising mom-and-pop places to switch to.

Any idiot can throw a filter and some grounds into a V60 and then pour hot water over it but really great pour-overs aren't easy. You need a high-end grinder and fresh, top-quality beans. You need practice dialing in. There's even a bit of an art to making the pourover itself, with blooming and stirring, weighing the output, and timing the draw-down. People pay to see a skilled barista going through the ritual.
