The AfD would support it? They seem like one of the more freedom focused parties in Germany.
In addition to that, the AfD is not known for being predictable.
The party lacks a strong institutional core. It is shaped by competing factions, with a weak internal agenda-setting process and a tendency to align with whatever the decision maker closest to making a statement currently perceives as fitting their brand. Positions often shift as a result.
For example, they made a strong commitment to protecting cash, then later pushed for a mandatory payment card system for refugees, explicitly to tighten financial control over that group. In practice, that dramatically helps to normalize financial control through payment systems.
So, TL;DR: no one really knows. They’re inconsistent and hard to forecast.
