Allowed? Technically yes, in the same way people are allowed to start local broadband co-ops or like grocery stores or whatever else.
The problem comes when you have to actually make people aware you exist and have a service or product for sale, and “compete” with the national/multi-national corporation who have infinitely more resources than you do.

Just look at how Walmart and now Amazon have put just about every mom and pop shop out of business. They can move in, drop prices so low locally long enough to put you out of business because they have other areas locked down already and covering the losses. Then once they have the market locked up they can charge whatever they want because you have no other options.

Almost certainly there already exists a non-profit health insurance organization, they just don’t have the resources to advertise on all the major channels and across the interwebs like all the predatory ones do.

It’s not really teaching Boys to Scout, it’s a program that is Scouting for Boys who are likely to do well in situations similar to the military, albeit a less modern one than exists today.

I know one anecdote doesn’t invalid proper scientific research but … erections and even orgasm is not impossible on MDMA. I (a guy) have definitely had a bunch of sex on MDMA, not always to completion but sometimes.

The paper you linked states this at the end of the introduction, emphasis mine:

The phenomenological features of the psychological state induced by MDMA ** show some similarities** with features of the post-orgasmic state.
…
Here, we ** present the hypothesis ** that the impairment of sexual parameters after MDMA may be mediated by increased prolactin."
