High compression engine creates heat. That heats up the cylinders, combustion chamber and sparkplugs. That exessive heat will cause the fuel to igntite aka detonation or pinging. Which the car doesn't like.

Sarcasm aside, the people who will be truly considering putting 87 in their car probably don't hit 100% throttle every day. And if you aren't using 100% throttle, you aren't using 100% of the available power. So will you miss it when its not there because you are now using 87 octane?
Pinging and detonation doesn't require 100% thottle load. Often it happens just on a moderate take off from a red light or up a hill.
