when clay is allowed to sit without disturbance it will come out of

Na is positively charged. Cl is negative. Which is exactly why salt
_isn't_ hydrophilic.

The clay forms an electrostatic interaction with water molecules, so in
that sense it's the same as NaCl. Luckily it's not as strong as an ionic
bond, or else our ponds would need to be very hot in order to be liquid

Ionic bonds _aren't_ strong - that's why they fall apart in solution.
