Yes, but in some jurisdictions the licenses are the only things allowing lawful use of the data (at least in sizeable portions). I'm concerned that we'd put some users, and maybe entire projects, at unnecessary legal risk if we ignore this.
You make it sound like we do not have a license in Wikidata. We do have a license, and this license allows the free reuse fo the data by any user or project without them running any legal risks.
