The keyword there being "unreasonable."  I don't think that clearly addresses the BOI issue.  It would be reasonable so long as the government had a legitimate reason for requiring the information.  Preventing tax fraud, money laundering, etc., may be a sufficient governmental interest.  

Besides, the federal court did NOT find this to be a 4th Amendment issue - they ruled it was likely unconstitutional under the 10th Amendment - that Congress exceeded its authority in passing the Corporate Transparency Act (CTA).  It found this to be a "substantial expansion of commerce power" because it really didn't regulate economic activity or non-economic activity among the states.

I still filed my BOI report... it only took a couple of minutes, and I don't want to have to worry about whether the law is ultimately upheld.
