That is exactly what I seek to prevent. Asking people to do things to prevent extremely rare occurrences doesn't work. Putting people in prison after a mishap is a sign of a failed policy. Drones already have a return to home function - pretty simple to have a "change altitude" function if they can get the information they need to do so when it's required. The absolute risk has been outside the 6-sigma boundary for normal aviation accidents. Requiring drone makers to add ADS-B In and evasion can move that to 7 or 8-sigma.
ADS-B Out is so no one has to see anything. In the US it just isn't universally required for manned aircraft and, for some manned aircraft, is prohibited.
