If you want to start a band, you can. Simple as that. No lawyers or permits or permission are needed.
However…
There is no guarantee that it will make you a living. You are not entitled to have people come and listen. You probably will get booed.
That is what being in a band is.
Learning to deal with rejection. Practicing. Getting feedback and getting better.
No promises but you do get to start.
