I never finished reading Sandman, but why did Morpheus hand over being the Endless Dream, to Hector Hall's son, Daniel? [cool to see him take his parents to the Dreaming after they died recently]

Definitely.
Assuming Jaspers needs to dream to begin with. (he can easily supress the concept)
But beyond that, why would Jaspers need to wipe out his own mind?
When Jaspers controls any concept within his warp, (like dreams)
and that applies to himself just aswell.
If Jaspers needed to wipe out his own mind to control/defeat "Dream" (a Concept)
then Jaspers would've had to wipe himself out entirely
to control/overcome Time & Space (616 Universe) which he warped.
A thought is not a dream though.
And that is all Jaspers needs to control any concept within his warp.
Morpheus = lord of all that's associated with dreams, [thoughts certainly fall into this catagory].
Anyhow,
The only real way MJJ could eliminate the concept Morpheus represents, would be to make everyone in his warp a completely thoughtless vegetable, [this includes himself as well].
Even IF Jaspers accomplished this, not only would he be powerless, but he would have only succeeded in defeating a Universal aspect of Morpheus, [whom is a Multiversal entity].

First time I ever here that my thoughts are dreams.
Thoughts aren't dreams.
Dreams take place in the subconscious.
Thoughts are produced in the conscious mind.
Jaspers can elimate the Concept of Dreams,
by twisting it's fundamental and/or abstract nature,
or simply by replacing the Concept with himself
(Like he did with all the 616 concepts)
Again, Jaspers can eliminate the Concept of dreams.
Or Jaspers can replace the concept with himself.
Or Jaspers can create a Reality where the concept of Dreams is non-existent,
or inconsequential.
So many options for one who is,
Jaspers = lord of all Reality in his warp.
This is under the circumstances that You personally have created,
where Jaspers would need to make everyone a vegy including himself.
The fact is, that Jaspers was proven to be above Concepts on panel,
like becoming the 616 Universe.
Jaspers was above Merlyn,
who has manipulated/controlled every concept in the Omniverse.
Jaspers can negate or allow any and every aspect or concept
that's part of Reality within his warp.
eg. Jaspers doesn't have to erase your intestines,
to create a Reality where no one needs to take a anymore.
Because if he wishes it, it is, no matter how irrational or illogical his whim.
It begins at the Universal level,
and soon enough the Multiverse would be next,
and then the Omniverse.
