Agreed, its not all about Fuel Savings I have a Prius Alpha since 2014, ofcourse it required ABS & HV Battery replacement but the utility, comfort & safety(8 Airbags) that it provides isnt there in local cars thrice its price.
Fuel Savings are there ofcourse offset quite a bit of the maintenance costs but maybe not completely, in short "to each, his own". Theres are pros and cons to everything in life.
If you dont like it, Dont buy it. No need to heat up debates.
