Is there any way that Wizards could get around the reserve list by actually making digital power redeemable for a new piece of cardboard power? I imagine this would be somewhat similar to the way they were using the Judge Foils programme pre-loophole-closure, but I'm curious if the buying of digital commodities is an area fuzzy enough in law for them to exploit should they so wish.
That will never happen. Ever.
It's not a law thing. They could print power right now.
The answer is actually yes. The Commander's Arsenal set included oversized foil Sliver Queen. They could reasonably print oversized foil power.
