I know exactly what you mean. You hit the nail on your head. It's like "Oh, why do I spend so much time worrying about little things". It just grabs the shit and dumps it out. It's the greatest perspective on life and love and the best way to reorder your priorities.
I only later learned more about dosages and found that the downsides are at higher (1.5mg/kg+) doses and with long re-dosing
Besides, if you would have read the article - they are mentioning dosages of 125mg.
I would also be confident enough to say that MDMA is not as linear in dosages against body weight and _almost_surely_ it depends way more on your digestive than your body mass.
PS: to be clear, I did this with people who were multiples of my own weight (68kg) and incredibly petite ladies who were smaller than me. Dosage has little correlation with the effects they would get.
So I’ve got a feeling that your point comes from reading some info on the internet, rather than your own experience.
I can't believe I'm saying this on HN, looks like it's finally just another subreddit: I have plenty experience, sure.

Edit: my apologies, I didn't see the /kg part of your equation. After doing the math, yes that seems like a reasonable beginner/small dose.
Always start with a low/threshold dose first and go from there (this might be less practical for MDMA, where you want to limit repeated exposure).
Smaller girls I knew would be fine with 100mg doses and big dudes would need about 200mg or so. Most people would do 125mg - 150mg.
Went out one weekend and had a mid-range dose of MDMA and with the afterglow in the days later I felt like a new person, complete with a spring in my step.
It felt like I had been hoarding a lot of useless stuff in my mind and never being comfortable in my head, while MDMA was the clear-out I needed.
I wouldn't advocate for each depressed or anxious person to try it as a cure-all, but I definitely advocate for more research (and have donated to the cause) and greatly reducing the stigma around the drug
