Sometimes society established norms when doing a thing was very rare and expensive, and honestly barely needed any control because it was so unusual. If that thing becomes a lot cheaper and easier, and it starts being done a lot more - perhaps we realise we actually need different rules even though the difference is purely quantitative. One guy juggling chainsaws on main street - how entertaining! No need to ban that. Dozens of chainsaw jugglers on every street, 24/7, the issues are easy to imagine. To say that "Oh, you were OK with one chainsaw-juggler therefore you would be OK with 100,000" is IMHO a line of argument that obscures more than it clarifies.
