I, and am sure many others, have plenty of semi-auto handguns/rifles meant for self-defense in case of SHTF. I am also sure most of us have been paying attention to gun bans of various sorts, especially those that want to ban or severely restrict access to/possession of semi-auto firearms. I like to have backup plans. Whatever happens to my semi-auto firearms, whether they get registered or confiscated or buried or whatever, I have a substantial investment in the ammo for those firearms - less so in ammo for my revolvers/lever actions (e.g., .357 mag, .30-30). While those other hunting/etc. firearms can substitute for the self-defense firearms, they are not optimum for that purpose and their ammo may not be either. I think it is probably a good idea to have a backup plan. E.G., acquiring firearms chambered in 9mm, .308, 5.56, etc., in firearms less likely to be subject to restrictions.
