Consider that if you take off with the heading and start to wander
into some obstacle, tower won't be able to do anything about it
(because they won't know) and neither will the approach control

That's where the period goes. Approach may know, but may not be able to do
anything about it.

until
they get you on radar, which will happen at various altitudes,
depending on where you're departing from.


Radar coverage and "radar contact" have nothing to do with terrain
clearance, except when above the MVA and a vector is issued. Even then there
can be errors, so it's wisest to always know position relative to terrain.

I believe that there is a HUGE pilot misconception about the level of
assistance for terrain avoidance when departing a towered field.

I have learned to always request and fly ODPs when they exist, no matter
what kind of airport, or weather. It's good practice. I believe that the
same applies for SIDs as a way to reduce the risk of metal to metal contact.
