No... security depends on the cost mounting an attack, and that's the absolute cost.

  No... a chain that costs $1M to attack with a mktcap of $100K is more secure than a chain that costs $10M to attack with a mktcap of $100B, as the latter has huge financial incentives for doublespending (after depositing say $100M at an exchange), while the former has none. It's like how much you spend on a bike lock. A $100 lock on a $20 bike is probably quote secure, while a $200 lock on a $5000 bike is probably quite insecure.

    No... an attacker that is able to successfully execute a 51% attack can crash the token price and make enormous profits in the derivatives market, so the market cap is irrelevant. Moreover, and attacker may have motivations other than financial gains, which again makes market cap irrelevant. If your security model only protects against financially motivated attackers it means it's basically rubbish.
