How do you find the limits of areas on a chart?

You don't simply 'pop' into a largely empty area of a chart.

I don't see any difference between the two.

There go those blinders again!

The charts have numerous landmarks - lakes, rivers, roads, power lines,
cities, racetracks, aqueducts, quarries, bridges, antennas, hills,
mountains.

Not enough to locate the boundaries of the airspaces.

If you know how to read a sectional properly and can see out the window 5
miles in each direction or more (10 miles total) you should be fine.

All are very discernable from the air in real life. MSFS does not
effectively simulate the real-world view of the ground from the cockpit
of a small plane, and that is why you are having so much trouble.

No, I'm having trouble because there isn't anything on the chart that
allows me to locate airspace boundaries in many cases. The boundaries
are not stenciled on the ground outside the window, even in real life.

No, you are having trouble because you don't know how to read a sectional.
That became obvious in your question about the Turtle MOA.
