Why don't the Gorosei vandalise the poneglyphs? Or steal them?

Do they know where they are? They could easily get the ones in Skypeia, Arabasta and some others. Well, I'm not sure if they could get to Skypeia easily since you have to go on the Knock Up Stream or the Summit of High West or from other sky islands (coming through other islands wouldn't be very covert though). High West isn't as dangerous according to Gan Fall, so they could've done it I guess.

They could just send CP9 or CP0 to steal them? Can't Blueno take them into his dimension and then bring them somewhere else?Even easier if he can take a trolley or forklift with him in his dimension, if it can store items.

Or just send CP9 to paint over them. Or get Fujitora to send them into space. Or if they have the tools to cut seastone, do that?

Since Kaidou is defeated, they can go to Wano and get the poneglyph there. Or maybe they don't do it because Wano is the only country that knows how to cut seastone and the marines and celestial dragons need seastone items.

They may not know about the whereabouts. The government has never had reason to go to the sky islands that we know of. The ones at Fishman Island are strange though, they are in the middle of a big field completely exposed lol.

But yeah, you'd think with how far the government is willing to go to suppress knowledge of the past, they'd try a little harder to locate them and take them away.

Though it shouldn't stop them from moving them. Maybe they don't wanna ellicit too much attention. They also likely don't know most of their locations.
