As I see it, we've merely discovered a "digitized" way of scribbling on our fungible e-cash?
The shitcoinery aspect of inscriptions occurs when the shitcoiners try to convince you that "I used this to snort cocaine" makes the dollar more valuable.
No, it's still a dollar, you just scribbled nonsense all over it.
Perhaps "scribbling nonsense" digitally onto a bitcoin has greater significance that my pea brain doesn't comprehend right now, but all I've seen so far is other pea brain humans using it to psyop.
