Easy. Each weapon is a tool that will likely never be used, but if it is must be 100% reliable and quickly deployable while under extreme stress. "Smart" guns introduce a new feature that would impact both speed and reliability.
No implementation of a TouchID-like system for guns would be perfect and so the gun owner must weigh the potential benefits and risks. I don't think the NRA's members want to take that choice away from the gun owner, but even having a commercial solution come to market means some states will require it's use. IIRC one state has laws on the books to mandate the use of the technology once it's commercially available.
