I think "increased regulations" is a wide spectrum. Extremes (I believe) are rarely a good thing.
"Confiscate money from all people in Casino" / "Confiscate all Bitcoin" are, I believe, extremes.both
"Issue licenses for gambling, provide oversight, age restrict, run information campaigns about dangers of gambling, create support and help programs", is, I think, reasonable (and we can further discuss details, and we do; "Are loot boxes gambling"; "should state / group X run casinos"; who and how should be able to gamble, what is the right amount if disclosure, what is an informed responsible consenting adult, etc. All good things for us as society to honestly discuss).
"Ensure bitcoin income is taxed (like every other investment), that it follows disclosure rules (like every other investment), that it is open and transparent and licensed, etc cetera", is I think reasonable and merely catches up the playing field and closes off loopholes that EVERYbody knew were temporary loopholes (and smarter people than me can discuss details). "Government should not spend gazillion dollars blindly investing into this technology hoping to find problem to solve" is also, I think, a statement I'd stand behind. And not unique - there are MILLION fads or technologies or endevours I don't want government to invest in, so don't feel picked on :)
IF that latter option still somehow causes everybody involved to lose money... well ain't that just food for thought though, right? It means people were literally banking/hoping/assuming they can do things without oversight and through magical loopholes forever. I don't want to say "illegally" because there may or may not have been a law in time with new technology. But crypto and bitcoin are almost as much fun to discuss as religion with a Christian apologetic - it gets all shifty very quickly; it is and isn't investment, or a transactional system, or currency, or stable, or volatile, or private or public,or efficient, or safe, reversible or fixed, etc etc depending on needs of the moment and which point we're trying to make.
I don't see anything synonymous with "Confiscate" in that letter. I see it as a small attempt to counterpoint the massive over-enthusiasm, bluster, lobbying, and tall tales that abound around crypto (there may or may not be a nugget of useful technology, use case, future approaches in blockchain; willing to discuss that; but anybody that rejects the observable amount of scam and dishonesty in today's actual crypto implementations, investments, sales pitches and pushes and frankly disinformation campaigns, is not having an honest conversation with me and/or is trying to sell me something and/or has been sold/swindled themselves).
