The use cases for a single IP not associated with your person are numerous: avoidance of ISP retribution for your use of certain network connections (ie torrenting), avoidance of direct targeted attack, avoidance of geofencing, avoidance of censorship by IP location, as a few examples. All the better if the private static IP can be changed on demand and adjusted for location.
Does the IP on the instance change on a regular interval? Or do you have to request it? I use VPNs to protect against tracking. If the IP is mostly static then using it as a defense against tracking is useless.
