Isn't IPv4 good for privacy? My IP address doesn't uniquely identify me unless you get records from my ISP. But wouldn't I be more likely to keep the same IPv6

Isn't IPv4 good for privacy? My IP address doesn't uniquely identify me unless you get records from my ISP. But wouldn't I be more likely to keep the same IPv6 address consistently? It also makes it hard for websites to block users based on IP without also blocking lots of legitimate users sharing that IP. I think this is a good thing to keep the internet more equal and anonymous.
