I would not want walking far on foot to be illegal just because most people who actually did that were doing so to further a criminal goal, no. That is how we slide into authoritarianism.
It's the same reason I want a right to privacy; you could argue that most people who want to hide something from the state want it because they're doing something illegal, but I still find it valuable that I can do things without being tracked. It's the same as the right to go outside without any form of ID; most people who aren't up to anything illegal could make sure to always bring valid ID at all times, but I value the freedom to not be forced by the state to bring something. It's the same reason I would oppose a law that you must wear a GPS tracking device on you at all times; most people do it willingly with their phone and watch these days, and the only people the law would really affect would be criminals, but I value the freedom to go somewhere without being tracked.
I currently make all payments electronically, but I value the freedom to be able to transfer money without leaving traces of the transaction, even though I don't currently exercise that freedom. Because the state doesn't have any business micro-managing individuals' behaviour like that.
