How do I relate it to the real world? In other words, how do I know,
as I fly along, whether I'm inside or outside a boundary? Very often
the boundaries cross largely empty areas of the chart, with no precise
indications of how to locate the boundary in the real world.

"Largely empty" is not the same as empty.

If the latter, when all else fails, some pilots fall back on an advanced
technique that is all but forgotten in this age of GPS. It's called
"looking out the window for landmarks."

But the charts don't have that many landmarks, and the boundaries
rarely seem to be based on landmarks; instead, they seem to have been
surveyed.

There are more landmarks there than you think. Why don't you pick an
example of a boundary that you're having trouble with? Talking about
this in generalities doesn't seem to be productive.
