> The vast majority make $20 parlay wagers here and there and they're the real cash cow.

You got the meaning of "whale" wrong. The majority of the winnings / losings come from the "long tail" addicts.

> And then there are the degens that make $2,000, or $5,000 wagers on everything because [they are addicted]

I think my edit more accurately reflects what is going on.

You need to put more time into the proposal if you want to make it serious. How long would it take for people to learn they need "alt accounts" to gamble?

Suggestions:

1. Ban advertising of gambling.

2. Ban "remote" gambling including phone apps.

What would it take to make progress on this in the current regulatory environment? Post a link to someone who has thought about it.
