Outside transparency is not a benefit. Most people I've talked to about crypto don't see the opacity as a detriment. They do not trust the government or tax policy. Most of these people are also generally happy to pay their taxes but can see reasons when they would want to hide their behavior.
Lol, the common man isn’t really subjected to other forms of taxation.
Most people pay two kinds of taxes: income tax, and sales/use taxes (with property tax being a distant third).
The most common taxes are difficult to dodge.
Edit: I am again talking about capital gains. Yes, the money has to come from somewhere, but you can break the traceability easily by using non-kyc means of getting crypto. E.g. bitcoin ATMs.
People keep walking this back to massive fraud but more likely what anonymity will do is just allow businesses to escape onerous operating issues. E.g. having employees in some states is worse than having them in others because of those state's perceived requirements to operate an LLC in that state, and other related rules. It's not even clear if some of these requirements are enforceable federally.
As I mentioned, there are more defensible reasons for only having one party lie, like avoiding CA's (future?) claim that paying someone who lives in California implies you hired them in California and need to incorporate in California.
BTCs blockchain is rather power inefficient.
Pfff, a single transaction is only 1700kw/h (or 820kg of carbon dioxide) with as little as 90g of electrical waste left behind on average. From an economical standpoint that could be much more ... if you are to sell energy or equipment of course. /s
I think his point is: Bitcoin explicitly takes a libertarian position to taxation by making it hard to tax. While most crypto adopters may be libertarian, the majority of people are not and so the libertarian position will deter adoption.
As noted many times here, anonymous crypto is only as bad as cash.
