An person reaching their state's age of consent is adult enough, but 18 has long been considered adult. You can't keep a person a child forever. That's how you get 35 year olds still living with their parents contributing nothing to the household or society.
26 seems arbitrary. I wonder why that age was selected. I wouldn't vote for that late age. I did dumb sh!+ when I was 18, regretted choices I made, but I took my lumps and lived with the repercussions, blaming no one but me.
People need to start taking personal responsibility for the choices they make and living with the consequences of those choices.
An adult can do whatever they want to themselves in a free society. If you do something you can't undo and change your mind after - that's your problem.
So, I will tack on an addendum to my normal leave the kids alone.....leave the adults alone.
The government has no business being involved in a person's life to this extent.
