I've hosted a home game for a few years and haven't lost or had a chip stolen, yet. I think that's attributed to two reasons: 1) most of the regular players were green at the beginning, so they've been trained to respect the rules of play (don't take chips off the table, only I can access chips in the bank for rebuys, etc.); 2) they all think I'm a little nuts when it comes to my poker chip fascination, so they dare not tempt the outpouring of wrath if I'm one chip short at the end of the evening.
A lot of it has to do with the type of people who are playing, too. I have 100% trust in the players I invite into my home, so I'm not worried about theft. And, since we don't play on carpet, everyone can hear when chips fall on the ground, so losing chips is highly unlikely.
