Question insulate attic and install plywood?

Hello, I apologize if this is a repeat question.
I was told that my house attic needs more insulation. I have planned on rolling out insulation perpendicular to the joists. But, I have several sheets of .5" plywood up there so I can store various things.

Should I remove the plywood and insulate? Or insulate around existing plywood

Can I replace the plywood over the new insulation? Squishing down the new insulation

Any other affordable alternatives?

Thank you,

Remove the plywood and insulate it all. Don't put it back though and squish the insulation, that just lowers it's effectiveness as if it wasn't there.

You could use some 2x4's, cut a bunch of say 10" lengths and screw them to the side of a joist so they act as posts, extending 6" up. Place the plywood on that (and screw it down) and it doesn't compress the new insulation under it. You'll just have to cut a few notches in the insulation batt to fit around the posts. I'd suggest 5 posts per sheet (1 near each corner and 1 in the middle) .
