Additionally, if old concepts no longer work, then let’s get rid of them. Many will say, however, that these old concepts didn't work precisely because they had no basis in reality (e.g., PHLOGISTON or HELL). However, the characters and events in works of fiction aren't actual or real; though they nevertheless prove to be useful in that they show people about, say, general kinds of situation and general kinds of character. Nonetheless, fictional events and characters are often (or always) parasitical on events and characters in the actual world. Such works of fiction work precisely because they indirectly refer (in the minds of the readers) to existents. Even the most extreme works of fictional irrealism must depend on these kinds of indirect reference otherwise the readers wouldn't relate to the work or even make sense of it.
Wittgenstein’s position automatically disallows all the meta-languages (or meta-language-games) which would try to make sense of the conceptual flux and chaos around them. We simply need to accept that it's literally the case that anything goes because each individual language-game formulates its own rules.
Laws are laws because they abide by essentially arbitrary and contingent rules which are themselves custom- or practice-relative. Laws are custom-built entities which have come to be seen as belonging to something beyond the station of mere rules. Laws are thus taken to be universal; though they are no more universal than poached eggs.
