Maybe read again, what I said, and then you know the answer. Yes I always carry my passport if I go out further than 15 mins from my house, same as my wallet and phone. As well most times my laptop and chargers. I do that since 10 years.
Everyone should do what they want but if you go out in Bangkok, specially at night, you are smart to bring it with you. I always have everything with me, to basically be able to leave the country, if wanted or needed. Clothes are easy to buy again anyway. I store my to-go bags at MRT stations.
Im used to always carrying my passport as it is a law in my country and I never had a ID card / always a passport.
