A standard trick in DC policy circles is to derail any policy by focusing on a "better" policy, which lets you imply the policy's advocates are stupid and/or cruel.
One reason to focus on something like debt reduction is that it is something Biden has the power to do, unlike most everything else. This isn't the only reason. It's good on the merits, too, for a variety of reasons, but unless you have a plan to get Mitch McConnell to pass your fantasy plan, then you are just trolling.
