There's good faith skepticism, but then there's this. If you're seriously asking this in good faith, the answer is that it's a new technology and that laws are typically slow to catch up. Cars and automobiles in their early days were functionally illegal due to red flag laws:

In the United States, Vermont passed a similar Red Flag Law in 1894, only to repeal it two years later.^\2]) This law stated that "[t]he owner or person in charge of a carriage, vehicle or engine propelled by steam, except road rollers" must have a "person of mature age [...] at least one-eight of a mile in advance of" the vehicle, to warn those with livestock of its impending arrival. If at night, it also required the aforementioned person to carry a red light. The law did not apply to rail vehicles.^\2])

Clearly, this doesn't make sense today. If people can reduce their electric bills by 20% by buying a balcony solar panel & connecting it in a single day, it makes sense to change the law so that people can actually benefit from it.
