This is far from true.
"In fact, research shows that the median age of U.S.-born tech company founders is 39, and there are twice as many entrepreneurs older than 50 than there are younger that age 25." [1]
That's an odd way to phrase it. Cost of living is only ever going to be one in many factors that contribute to the level of startup culture/community in a given city.
It's also worth considering how the cost of living and the maturity of the startup ecosystems in SF and London have changed over time. I dare say SF would have been comparatively cheaper back in the days when the startup ecosystem was forming than London is today. No doubt modern-day London faces additional challenges because it's already an expensive city and parts of the ecosystem aren't as mature.
In SF, is it possible to rent a single room 15 minutes walk from where all the tech companies are located for $800 / month? Because in London you can.
The "London Living Wage" works out to about £1200 per month, after tax. There are people earning less than this in London.
If the startup doesn't need to be in London they could cut costs significantly by being further out of London in the suburbs, or in a satellite town, and taking the train in when necessary. But this can put off potential employees. Maybe it could work at the beginning.
Of course finding a room like that and getting it over the other dozens of people who want it is not that easy, but that's a system you can hack too.

I'm curious as to how you can assess lavishness of spending of people walking by on the street; presumably you're very good at identifying branded fashion?
None of the creatives who reinvigorated the area can afford to live there anymore.
Also, London does not have uncontrolled urban sprawl. It is constrained by the Green Belt, which was designed precisely to prevent sprawl. This is one of many reasons property prices are naturally high.
