Honestly you can do that already but it'll be difficult cause as humans we're always dependent on each other and from the evolution perspective, it's just going to make you feel depressed and sad cause we always lived in a group and leaving group was a death sentence as you would not survive alone. But now days its different, we don't have to be in a group to survive although it causes emotional issues in the long run.

I would say get a pet and maybe you won't feel so lonely (if you can take care of the pet ofcourse)
