Nonetheless there's a non-zero effort and cost associated with taking 1000's of individual cells and assimilating them in to what can be thought of as a "pack": physically assembly, electrical connections, thermal management, BMS installation, etc...
While the "container" for the above may be a honeycomb chassis that then is banded as part a structural member rather than a set of modules in a casing, all of the above will be necessary to go from raw cells to a "car ready" assembly. Thus "pack" cost would still be more than just raw cell cost. It wouldn't surprise me if Tesla will lower the "pack" portion of the cost as a result of the architectural change, however...
