This is a straw man. Nobody thinks this.

There are several federal institutions which deal with domestic violence (alongside additional state and local ones). For example the National Resource Center on Domestic Violence, which is part of the Department of Health and Human Services, and has the mandate to “understand, respond to, and prevent” domestic violence.
The FBI can also investigate specific domestic violence crimes, but my impression is that it is not their highest priority.
Domestic violence is a huge problem and is famously underreported, underinvestigated, and underprosecuted. Probably not the best example you might pick; arguably having additional government agencies with the power to do something about domestic violence might make a positive difference. (Disclaimer: I know very little about this subject.)
OTOH, most corporate crimes do cross state boundaries and thus are within the jurisdiction of both state and federal authorities.
With respect to cigarettes, the product itself doesn't kill people. There are people that live for decades smoking multiple times a day. The secondary effects kill many people, but there isn't a sufficiently strong correlation to ban cigarettes outright.
