Insulation with no floor studs

Hello, just wanting to see what people think, I read somewhere about someone who skipped framing their floor and just glued the insulation straight down and glued plywood ontop of that since plywood distributes weight really well and saved them some money. Is this viable? I like the idea and Foamular has 25PSI boards and thats what id be using.

That's 25psi by itself, or 3.6 tons psf. And that goes up exponentially when you put plywood over it, so it's not an issue. I plan on 1/2 rigid, 1" rigid with PEX laid in and my snap together wood flooring right on top of that. All floating with no plywood. I'm sure there will be things secured through the floor at some point. I cut the insulation 1/8"-1/4" to long side to side so it is a snug fit and won't move.

Thats good news. I plan on gluing it down with loctite and the plywood over it with loctite to avoid any moving. Thank you

I put down 2 inch foam and then a thick sanded finished plywood (5/8" or so.) screwed the floor directly down into the floor beneath the foam.

Doesn't this make a thermal bridge though? Or does the flooring over the plywood cover it pretty well?
