Summary - if you simply turned an old 1988 car on and off all the time, it definitely would damage the engine and the battery and produce more emissions. But modern cars with auto stop-start are designed for this from scratch. Emissions are lower for the same reason.
If you're right - that this is bad for reliability and emissions - that would suggest some conspiracy from governments and manufacturers who are pushing for this.
