Some people really like exotics, but permits and such make it a pain to own wildlife (with good reason, however!). If they are kept in the proper enclosure and cared for the way they are supposed to be I don't see any major issue with it. Rats and other rodents started out the same as chipmunks, they were wildlife and were domesticated. If someone has the passion enough to go through all it takes to adopt chipmunks I don't see a reason to persuade them against it, even if there are plenty of domesticated companion pets to choose from. =P
Since they're on the topic right now I thought I'd share a photograph I took of a chipmunk on vacation a few weeks ago.
Also, y'all are making me want a hamster with all your cuties... I will have to live vicariously through your little munchkins!

And if anyone is curious, here is a dry herb mixture I give my boys;
(finally mixed it up in a jar a few days ago instead of opening each bag... so much easier. xD;
