when you make a bet, someone or some entity is fading you on the other side.
the same is true when one buys or sells options. just as you choose to
mitigate risk by taking protection when selling an option; others in
similar situations may or may not decide to hedge none, some, or all
of their position. different people have different opinions, strategies, risk
tolerances, and bankroll. one blanket investment strategy is not correct
for everyone. what makes you comfortable may seem too risky or too
conservative to others. that's why these markets take action on both
sides and derivatives are offered to allow one to protect or aggressively
invest ones capital.
