Not just emergency access and ventilation but the stations aren’t cheap or quick to build either. The tunnel itself is almost always the “easy” part.

From sf to la wouldn’t need stops in between. At most you’d need 1-2 stops in between. I could totally see this as cheaper than dealing with every land owner in between the train’s path

You still need to deal with every land owner in the path. Property rights don't stop at the surface of the earth.

Emergency access isn't necessary for Boring Company tunnels. They're so narrow that no one is getting out of a vehicle in an emergency in the first place.
And most of the cost of tunnels is the requirement for emergency access and ventilation; the small demonstration tunnel in Vegas lacks these features, and so was cheaper.
To compare, the Gotthard Base Tunnel in Switzerland requires emergency cross connections every 325m and access shafts to the surface. The cross connections are perpendicular to the main tunnel and short in length so they have to be dug out more or less with workers anyways. https://en.wikipedia.org/wiki/Gotthard_Base_Tunnel#/media/Fi...
