Wouldn't self hosting a VPN make you even more identifiable though? Now instead of an generic ISP IP address that changes every few months all your traffic is from a single static IP from a single cloud instance. Not to mention you're now trading your ISP seeing everything to your VPS provider seeing everything (and not just the internet traffic, everything in your server including the keys used for the VPN transport). And if at any point the packets exiting your VPS ends up back on your own ISP's network, they now know it's you who generated them because no one else ever connects to that server. I feel like a public VPN service would have slightly more anonymity simply because you're not the only source of traffic.
