Predictably gets several things wrong.
1. Gambling is a real addiction. It is quite strange that someone using the term "Addiction Markets" fails to understand this. People who are gambling addicts were gambling before it was legal, they were just getting their legs broken in a way that was non-visible to you.
2. If you ban gambling, the ability of people to gamble online is not reduced in any way. None. The US offshore market was the biggest sports gambling market in the world before it was legalised. Not even close.
3. I would take a close look at how offshore gambling operators work before casting aspersions about onshore. Onshore, providers are working with regulators to an extremely significant degree. Offshore, sites will advertise that you can gamble on their site if you are on an onshore ban list. If onshore providers are so terrible, why is this the case?
4. The attempt to say that lotteries are addictive is just nonsense. Generally, there is a very poor understanding of what gambling addiction is (again, point 1). Certain games are designed to appeal to gambling addicts (again, the most prevalent ground for these was...the US...before online gambling was legal, biggest market by far, almost all the large companies making these games come from the US), those games are harmful. Lottery, sports gambling, raffles, DFS, etc. lack all of these properties. In particular, providers will often use virtual events (virtual horse-racing) to try to mimic the properties of more addictive products (with relatively little success)...because the original thing is not as appealing to addicts.
5. It is correct that the UK has "stake limits" (not quite sure what the author thinks this...all regulated US providers also have these, some states also have deposit acks...which would be beyond the UK standard, I would say many US states are ahead of the UK) but this is only on certain kinds of machines. The author spills a huge amount of words, talks about Trump, talks about the 1980s...but doesn't seem to talk about these machines, which are more prevalent in the US, at all. The author doesn't say anything about the issues in the UK being the same. VIP programs in the UK aren't regulated in any way different to the US (providers have no market lists). There is one important difference: in the UK, the government has given gambling providers that powers to perform extensive background checks, they take your income, an audit of your assets and then decide whether you can use their product...people opposed to gambling never mention this. How does that fit with neoliberal? A company being given the same powers as regulators?
6. There is an issue with corruption in the US. There is no coincidence that the law on online gambling changed within a few months of one of the largest donors blocking this. Both sides benefitted from this as the largest Democrat donor in those years was the Las Vegas casino workers union. Again, because this corruption meant that some kinds of gambling didn't happen...no mention. This was, we now know, hundreds of billions in value generated by paying politicians hundreds of millions a year...no mention.
7. The author appears to be unaware that DFS existed after UIGEA, not "laughable"...just a basic understanding of the sequence of events.
8. Gambling is not inherently addictive. Many things that are legal in the US are not only inherently addictive, but are inherently harmful. Liberals care about you losing your money when you buy a $5 scratch-off, they don't care about you losing your mind with mind-bending psychoactive substances.
