I always buy this argument....to the extent that the more powerful, dangerous capabilities are still allowed but locked behind some (one time) process that indicates you have a base level of knowledge and understanding. If you want to make it default safe for normies, fine, but let me turn my own device into the dangerous thing it is capable of being.
The version of the your view that we are actually getting is _incredibly_ paternalistic and condescending to the general populace. The kind of society that is capable of protecting everyone from every conceivable harm comes with the kinds of tradeoffs that no one, not even the people who actually need the protection, are going to want.
