apstyle- i agree with you, mostly. some insurances are mandatory, no matter where you are: car, house, renter's etc. however, this thing with insurance on appliances? my boyfriend's nan has insurance on her 23 year old washing machine, fridge, boiler etc. works for her, but i'd rather have a savings account to dip into if and when anything breaks, need replacing etc.
the travel insurance thing- i would never travel w/o international health insurance. the cost of repatriating, etc would be astronomical. the lost bags, etc I think is just part of travelling.
