Yes. Making millions of them would likely also make all the other problems go away. Wit a million copies, we can forget about the controlled re-entry. While

Yes. Making millions of them would likely also make all the other problems go away. Wit a million copies, we can forget about the controlled re-entry. While around 700k of them will sink in the oceans, there should still be 300,000 that will fall on land. As long as the initial orbits, drag profiles, heat absorbtion profiles/patterns, etc. are sufficiently randomized so they all truly re-enter in a random pattern, there should be no need for propellant, engines, power, or controlled re-entry.
