... it is just your personal desire and it does not go along with what is good for society.
in whose opinion? yours? what is good for society is a complex question and i'd advise anyone to be deeply skeptical of anyone who claims to have the answer unequivocally, as your comment here suggests.
some level of regulation is required in most things that are truly shared public resources, like roads or the airspace, water, etc. the question then becomes how much, what type, at what cost - to who - and what benefit - to who?
personally, i'd say the highest priority in the states is to get people out of their cars, onto bikes or similar, using less land and energy for getting around, parking, etc. anything that significantly moves that needle has a huge public benefit. it gets tricky when the system is so lax that it creates a very strong negative perception, which REALLY limits the potential market and benefit. not too many people are going to think "hey i could easily get to work/school/the market on an ebike" when their only experience is of nearly getting mowed down on a sidewalk or crossing the street. similarly, the strongest advocates for e-bikes COULD be the millions of existing cyclists in the country, but the poor behavior of a subset of e-bike riders, especially when using infrastructure that traditional cyclists fought long and hard for, has alienated a huge number of those people. add to that the inability to reliably regulate things like this at a federal level (by design, really) in the united states, and we're goin to see a patchwork of opinions and rules for a long, long time.
