comment Do all massive bodies emit Hawking radiation?
It seems you did not read the question and comments to other answers. Your stand that "no horizon=no radiation" has been already addressed by a conjecture that the horizon can emerge virtually.

comment Will entropy continue to increase even if the universe begins to contract?
@ACuriousMind all new theories are usually tested against holographic principle and if they contradict it, the theories are usually discarded.

comment If the expansion of the Universe accelerates, why its horizon does not shrink?
@Asher Holographic principle usually assumes that the total entropy of the universe is equal to the area of its boundary. Since entropy of universe grows, the horizon area also should grow. For instance, this answer by Ron Maimon claims the entropy of the universe is equal to the area of the cosmological horizon in Planck units: physics.stackexchange.com/a/36121/1186

Is it good or bad compared to other materials? What about water in isolation from CO2?

comment Possible paradox with black holes and time dilation
An interesting interpretation would be that 1) Yes, Alice is frozen on the surface for infinite time, yet 2) another Alice inside the black hole that was sticked to its surface from infinite past (we assume eternal Schwartzshield solution) unsticks from the surface and falls to the singularity. Something like this.

comment Is the Schwarzschild black hole unphysical?
@Ben Crowell the horizon is null.
