[Harry Potter] How much rights do muggle parents and guardians have over their magical children?

So in HP and the Philosopher’s Stone, Vernon and Hagrid are exchanging barbs when Vernon announces that Harry will not be going to Hogwarts with this exchange;


“"Haven't I told you he's not going?" he hissed. "He's going to Stonewall High and he'll be grateful for it. I've read those letters and he needs all sorts of rubbish -- spell books and wands and--"

"If he wants ter go, a great Muggle like you won't stop him," growled Hagrid.”



So it got me wondering, how much rights do parents and guardians have over their own children in the magic community?


Harry was entrusted in the care of Petunia and Vernon. And while they weren’t great guardians, they had all legal precedents over the boy and his raising.  


What authority does Dumbledore have over a parent’s right to their children, not just to Harry, but any muggle parent who may not want their child to go to Hogwarts?

Remember, the muggle and wizard governments barely interact. From the ministry's perspective they have no legal rights over harry. They only have those in the muggle world.

The Dursleys can't physically stop powerful wizards, and they have no legal recourse- the muggle government won't be able to do anything even if they believe the story, and the wizarding government is still discussing whether to acknowledge muggles as people, never mind respecting their legal rights to parenthood.

The wizarding world seems to respect muggles rights, but its in the same way we respect a mother animals rights to their kids- they're being nice. If they want to take kids to hogwarts forcibly, they can.  They don't want to, seemingly, but they can.
