Esp. as addresses tend to be dynamic.
Well, it depends - a lot of direct consumer cable and optical fiber Internet connections have fairly stable static IPs that rarely (if ever) change. Big companies though, or universities, are often run with a pool of IPs. And mobile devices usually get a new IP every time they log on, also from a pool.
So there are plenty of ways to circumvent IP blocks, even without getting into the more technical stuff like Tor or anonymous proxies.
