It's a simple cost benefit factor. I believe for a certain period of time
in the 70s, most Piper trainer aircraft came stock with only one radio. It
was adequate. In fact, it was an improvement over the light beacons of the
early flying days. But believe it or not, people were able to navigate
successfully by air even before there were Radio Navaids... And if they
made a wrong turn, much as in a car, they turned around and found their
way, or stopped at an airport and asked for directions.

Them's the good old days. Technically it's still perfectly possible
today, but it's a lot more difficult procedurally. After all, you
used to be able to fly without a license, too. Today you can still
fly without a license in theory, but it won't be legal.

The very first link offerred by a google of "free Sectionals" produces a
link that will satisfy your need. Took me all of about 2 minutes to find.

I get "AHS Roundup: Three teams line up MIAA Tourney spots" as the
first link, and nothing on the page that references aviation.
