Tourist,
we are accustomed to a "minimize risk" environment. It is hard to argue that UAVs pose "no risk".
Your blunt statement is...true. It is about relative risk - how one dangerous thing compares to another dangerous thing. You cannot fight all battles - pick the ones that matter.
Imagine the horror when motor vehicles became available! ANYONE could go get one. You had to have a flag man walk ahead of you (the government's feeble attempt to use railroad rules to control the automotive dangers).
Society learned, to a point, to cope with this invention. People continue to kill themselves and others with it. It is acceptable to society. Not banned or outlawed. Controlled - but not even to the best of its abilities (we could mandate self-driving-capable car technology, so that technology could overrule driver input, when the latter is stupid or dangerous). We choose to use this with very, very much restraint (stability systems etc., but no automatic limiter to speed limits, for example).
Good post, Tourist.
