The chart has a metric butt load of landmarks. Hell, I'd go so far to say
that it is mostly landmarks.

I don't see that many, but even if that were true, do you really have
time to continually check them all to see how close you are to nearby
airspace boundaries, while in flight?

As a matter of fact you do.

For this example the restricted airspace is on your right. You know that on
your track the closest you are going to come to a given boundary is at point
X. You would look at the chart and find something or group of somethings at
or near point X and then make sure you fly to the left of them.
