I imagine the slogan is something like, "Reduce > reuse > recycle > compost." Just because PLA biodegrades doesn't make it more environmentally friendly than other sources of reusable underwear that also biodegrades.... Printing durable textiles at home sure would be cool, though.

The theoretical advantage of biopolymers isn't just that they biodegrade, it's that they biodegrade into materials (like methane) which can form the feedstock for bacteria which in turn produce the biopolymers. This is better than paper underwear because the paper->CO2->tree->paper cycle is much slower.
