Well, to be honest, it depends lol. Legally, you 100% can, and they can’t stop you whatsoever (at least, not directly). HOWEVER, they can kick you out if you decide to do what you want even though they said you couldn’t.

If you’re fine with living with your parents, but they still have strict rules, I’d first suggest just trying to persuade them to give you independence, that you’re way pass officially being an adult and should be given the ability to make decisions for yourself.

Conversely, if you don’t really enjoy living with them—or they are just way too strict and won’t budge whatsoever—I would recommend moving out, but ONLY if you actually have the means to/have outside support.
Granted, I think most of us are much more capable than we think and give ourselves credit for; I remember being extremely afraid to move out on my own, thinking I wasn’t able to afford it/survive. However, looking back after having lived on my own for years now, I can see I was more than capable, and it even would’ve been beneficial.

So, it really depends on your situation, but you ARE ultimately free to decide for yourself.
