The word "political" doesn't have no meaning, unless you take it to be understood as purely binary (i.e. "there are politics in this or there are not") in which case it's indeed a useless qualifier because, as I explained, there are always politics in it if there are humans involved. So yes, "x is political" is a useless statement because it is practically tautological in most situations where it is uttered -- but the same is true for "the Earth isn't flat", yet that's a perfectly sensible thing to say when dealing with Flat Earthers, just as "everything is political" is sensible to say when someone claims it very much isn't.
You seem to have a very narrow definition of the word "political". I'd be interested to hear what you think that is.
EDIT: It's also important to understand the distinction between "x has no meaning" and "x is no useful distinguishing quality". "Political" in my book means "involves politics", "expresses politics", "manifests politics" or something to that effect -- which applies to everything humans do, including what humans write, especially when they write about other humans. That's meaningful. But the qualification of something humans do as "political" is indeed useless just as qualifying water as "wet"[0] is generally also useless, because if those qualities are always present for everything in that category (i.e. all water is "wet", all human communication is "political") there's nothing the presence of the quality distinguishes any of those things from (of course water is "wet", hence why we don't talk about "wet water" and just talk about "water" instead, with the implicit understanding that because it is water, it is also wet).
[0]: Using the colloquial definition of "wetness" here. There are other definitions according to which e.g. soapy water is "wetter" than pure water but that's not generally what a layperson means when they say something is wet (i.e. is covered or soaked in water).
That's an interesting take since I refuted your points. You simply added a bunch of potential political concepts to something that wasn't political and then claimed it was.

If it applies to everything that humans do then there is no "involves politics" or "expresses politics". A human taking a shit isn't expressing politics no matter how hard the struggle is -- so I've just refuted that obviously over-broad point.
