I agree with the trans example because 1) it's a great example of one individual being allowed to do something that directly harms another individual; 2) it's fairly easy to prove that someone who grew up with male bone and muscle structure does not suddenly get the female structure because of a reassignment surgery or hormones. I am all for letting people do what they want with their bodies but their freedom stops at interacting with other people's bodies.

I cannot agree with the toddlers example: 1) it's possible it does some damage but as I said, to even consider it, we need proof; 2) even if they are bad at life, it doesn't automatically harm another individual - don't hire incompetents and they won't harm your business. They might harm society in general but society does not IMO have any right to force people to optimize for society's goals. The balance might change if this was true and happened on such a scale that society measurably declined but then I am still of the opinion that we should have mechanisms how a group of people should be able to get together separate themselves from others. We have no right to force the Amish to start using modern tech, even if a few more able bodies would probably be beneficial on some scale. Similarly, if the majority feed TikTok to their toddlers and a minority does not, they should be able and allowed to form their own society with its own rules, as long as everyone participates willingly.
