Good Lord. . .most of them are not in busy airspace and could function quite well without a tower.

Unicom, traffic pattern procedures and pilots using their brains and eyeballs is all it takes for safe ops.

Control towers are not essential even at busy airports as pilots can organize themselves, using air sense and judgment.

Pilots know the risks and take seriously “see and avoid.”

Towers are great for DFW, IAD, ORD, etc. . .but not necessary in San Marcos and the like.
