Calling I2C a "bus" is a huge misnomer. Almost all I2C devices have static addresses and the few that don't only have one or two changeable address bits. This means that you usually can't have multiples of the same type of device on the bus and there are several non-similar devices that share the same address, limiting those too. Why have addresses if you need a "bus" for each device? There are address translators for around $8 each, but you need one for each device save one.
