I agree with your statement, and cursive has extra benefits like leading to better hand strength and so on but outside of that, signatures aren't a good counter argument.

Signatures aren't cursive, they're a curated, custom art piece.

Arguably even signatures are being replaced with digital agreements. Just click "I Agree [and we'll use other proof than the squiggly that it was you because your digital squiggly is uselessly different every time]".

Arguing that something is good because Texas is doing it is ultimately a self defeating argument that reveals a lot about you (as do the other internet incel horseshit and exuberant defenses of Scott Adams' racism and misogyny you post). Do you mean systematic institutionalized racism, rampant gun violence, and frequent school shootings are good too?
