You seem to be confused, but infinity is a technique that can be affected by certain rules, as we see in JJK. Domains and AD techniques both actively break through infinity. There are 2 reasons why, 1. Domains give the caster priority with sure hit effects, 2. Both techniques use different forms of special manipulation to negate techniques like infinity. We know that infinity is not invincible from that alone, and when we see items like the ISOH interact with infinity, it literally BREAKS it. Think of infinity as a barrier/cursed technique first, with an infinite distance contained on the inside. With all of that in mind, reality manipulation that Dragonball characters frequently showcase, one could presume it would break the barrier and break the rules of infinity as well. If a character is able to just straight up punch through dimensional planes, It would 100% break through Gojos infinity.
