grounding - Should there really be 1 MΩ resistance between an anti-static wrist strap and a pc?

My previous question: what exactly is grounded through motherboard standoffs?

The answers suggest that a PC case is grounded in 2 ways:

1. To the ground plane of the motherboard, through the brass standoffs.
   
   
   
   • The ground plane is grounded to the PSU, through the ground wires from the 24-pin power connector.
   
   
   
   
   


2. To the PSU case, through screws. (Or surface-to-surface if PC case and PSU case are both unpainted.)
   
   
   
   • The PSU case and internals are grounded to the earth prong.
   
   
   
   

Q1: Is this correct so far?

OEMs like DELL advise to "touch an unpainted metal surface." Thus, when you touch the case, you are directly bonding with:

• case


• standoffs


• ground plane of the motherboard

But when you attach your anti-static wrist strap to the case, there is a 1MΩ resistance between you and the case, because of the 1MΩ resistor in practically every coil cord that comes with a wrist strap.

So, apparently, touching the case, without a resistor, is fine. But a wrist strap should be bonded through a resistor. That's contradictory.

Q2: Can bonding to the case, through a coil cord without a resistor, do any harm to hardware components?
