@Jennifer I think shooting things into orbit is regulated. That's why SpaceX has to ask the United States of America Federal Aviation Administration for permission before they do it.

Except the United States makes up only about 4% of the world population, or represents about 6% of the world's land area.

Yes, Starlink is available also outside of the United States, but even so... it's quite a gap from there to @sundogplanets's figure of 63% of active satellites being Starlink.
