Has NASA Lost Focus?

In the last 2 weeks I've seen several, well exotic is the polite word,
proposals from NASA. They include:

1) Grabbing an asteroid robotically and parking it in lunar orbit for
eventual manned visit

2) Starting nuclear rocket programs, maybe more than one.

3) Skylab II

4) Director Bolden talking about Warp Drive and beyond Mars

5) an EM-L2 visit (trip to nowhere)

Plus the existing things already in work like SLS & Orion.

Is this just the "run it up the flag pole and see who salutes" thing?
Different centers competing? Lack of direction from Headquarters?

Is there any consideration of the budget in any of these wild ideas?

It just doesn't seem to be a properly run organization with a focus on
worthy manned space activities.
