Can you get most of your needs met within 15 minutes walk in your town/city? Are your public transport links good enough to get to places you need to be within 15 minutes?
What would be the reasons you would need to leave your area/town?
Many reasons for me. The biggest that might not be deemed a necessity would very sadly be the nature defecit I have within 15 minutes.
