It's not a problem. More another manufactured nuisance of the kind San Francisco seems to enjoy creating.
New Yorkers have brunch later, brunch boozier and--broadly speaking--brunch with a reservation. San Franciscans (or at least my friends in San Francisco) eat brunch at the crack of dawn at establishments that prefer lines out the door to taking reservations. (They may claim to take "reservations" at the door. Those aren't reservations. They're names on a wait list. Lots of waiting.)
It's a cultural factor loosely related to (a) recent population and affluence increases outstripping a locale's (b) ability to build new businesses in the midst of (c) a greater value placed on exclusivity than time. (It's also present in Brooklyn and parts of Los Angeles.)

Ok, yeah, that explains it
That, itself, tells you about the local culture.
A culture that responds positively to a line out of the door puts a lot of value on trendiness. This is (much of) San Francisco. (It's not true across the Bay Area.)
A culture that responds neutrally or negatively to a line out of the door either responds less aggressively to trend pressure and/or has fewer supply-side restrictions. This is New York. A line out of the door in New York tells me it's a new place that's still getting its act together, there's an event there that night, they're filming or it's a shitshow.
Instead, I can grab a coffee (or mimosa) while I stand outside chatting with my friends or wander around the neighborhood.
If you want convenience, there are plenty of places that take reservations or can take walk-ins immediately. Some of them are pretty damn good too.
Then leave for the smaller, but still not short, line at Waffle House instead because it turns out no matter where you are, meal-time rushes are a thing...
I'll grant the tiny apartments but I'll also observe that, in undergraduate, we had space for a sizable number of people in a shared kitchen area. If where you live once you start working in a tech job is a downgrade from college, personally I consider that a problem.
And do denizens of SF/SV eat brunch mid-week on a regular basis?
Here in DC, it's typically a Sunday late-morning thing, which aligns with the British origins of the term. Reservations suggested for swankier establishments.
Name the last time you went to brunch. Now name the last time you were so upset at a brunch line that it inspired you to bitch about it online, let alone make it a part of your job-sites pitch...
By 1pm there was a wait, but for the first three hours that spot is open, no big deal at all.
