Home care is for people whose needs are too complex for their family and village to meet. Mostly it's a hospice for the very elderly and for people recovering from illness or surgery. But also for people who have specialised needs, including people who have violent tendencies.
Violence is a medical issue and treated accordingly. Patients are free to come and go but when they are out and about someone may need to go with them. There are no jails as there's no crime.
With equality there's nothing anyone has that anyone else can't have. There's no need for stealing and with no money worries, violence is rare. The few who are violent are not criminals but people who need help and sometimes supervision.
