I&#x27;m having a hard time understanding why this is bad.<p>If people experiment on themselves, then it seems the worst that could happen is they injure themselves to such an extent they require expensive ongoing medical treatment paid for by the rest of society (if they die, they just win a Darwin Award).<p>There will be charlatans (as with stem cell treatments) who try and sell this to desperate people with terminal diseases, but that&#x27;s already covered by fraud statutes.<p>The upsides from human enhancement are pretty limitless and exciting in the long run.
