They are quite available.

You could buy, in the next five minutes, three different styles of baggy pants in three sizes each. They'd be at your front door in a couple of days. You could try them on, test out the fit and pockets, and return the ones you don't like.

If you live in a big city or near a shopping mall, you could walk into a store and buy some big ol' pants within the hour.

If by "less available" you mean there are more SKUs offered or shelving space dedicated to "traditional" women's pants, then yeah I'll agree with you there. But it's 2026, you don't even need brick and mortar, and you can just order whatever you want.
