>It's a very common form of countercultural resistance and therefore an important relief valve. It's a way for anyone to express themselves on their environment.
So, what are these random scribblers resisting, exactly? It's like saying that defecating on the street is a form of self-expression and "leaving their mark". Even if it is, do we really need to tolerate it?
>Not to mention, it's lovely to be connected to a common thread of humanity over literal millenia.
There is nothing lovely about seeing all this garbage littering the walls of public buildings and historical finds do not justify this behaviour.
Resisting the ideology that only people with money can alter the city environment.
When you see an impressive sculpture or skyscraper you know a lot of resources were spent, you know the rich people here are rich. When you see an area with lots of graffiti, there may be many good or bad things about it, but you know the citizens are free.
I would hope graffitiers have respect to only draw on the mundane parts of the city, not on cool sculptures. And in my experience, that is true. Also they should not obscure windows or information signs.
>Even if it is, do we really need to tolerate it?
People not only tolerate, but I'd argue most people prefer it. I think, unlike Singapore or Tokyo, Americans, in cities, largely prefer a little lived in grime.
The Mission Bay is a relatively new neighborhood in San Francisco - mostly free of graffiti and is pretty much sterile, and most people would prefer to live in the Mission rather than Mission Bay. OpenAI likely pays a huge premium to HQ in the mission rather than settling in the more corporate offices of Mission Bay or even the Financial District.
I also noticed the same in Berlin - Kreuzberg, Neukolln, and other neighborhoods in East Berlin attract the most people, despite being drenched in graffiti.
If ever move to a city in America and tell people you live in the generally clean, spick and span, neighborhood in that city, half the people will look at you like you have 3 heads or simply assume you have no personality. Graffiti has largely become an accepted, or even valued, feature of a neighborhood. I believe internally it separates the "cool" city inhabitants from the "losers" out in the suburbs.
Edit: I just looked through all the images in the OP and one of them is a banksy. It's been there for over a decade. Graffiti isn't just tolerated, its practically protected.
> So, what are these random scribblers resisting, exactly?
The idea that the city is owned by the uppermost caste of that society.

Massive cathedrals to the rich would be erected and made holy, and individuals upon whose back society is build would demonstrate that though entrance is barred to them, they still can make the thing their own.
Nowadays there's plenty of such things in a city that closes its doors to many people that live in said city. San Francisco is a great example of this, where rising costs are pushing anyone not working in tech. Graffiti is an easy way to spit in the face of the rich that are trying to take a city away from you. Clearly, it has an outsized impact on their sensibilities.
