It seems like the purpose is to have the law and all the paperwork set up as a precaution for the future. Sure, right now it’s all voluntary and just rubber stamping, but if in the future they need to do something like Ukraine and lock down travel for military aged men, it’s much easier to flip a switch and start denying travel permits rather than having to set up and fund an entirely new system for requiring travel permits.

If it were to get closer to war (i.e., Spannungsfall, let alone the Verteidigungsfall) a set of laws would unlock that allow control of various areas of life and the economy anyway.

Interestingly, the travel permit requirement already existed in law before, but it was tied to the Spannungsfall/Verteidigungsfall conditions.

This new law removed this condition and preemptively "activated" the requirement even before the Spannungsfall was declared.

Also, in that case, they know where all the men currently are, which is probably the main reason to implement it now. m

Well that’s the thing, they won’t know because nobody will do the registration until it’s actually enforced.
