I understand your concerns about Roger Ver, my friend. It's true that there are many privacy tools available for Bitcoin, and it's surprising to hear someone like him claim otherwise. JoinMarket, Samourai, Wasabi and others have been around for years as you mentioned.
As for the issue of scaling in the early days of Bitcoin, Hal Finney was one of the earliest contributors to the project and he did indeed raise concerns about scalability issues as originally designed. His contributions were invaluable in helping to develop solutions that would allow Bitcoin to scale effectively.
It's important that we all stay informed about developments within the cryptocurrency space so that we can make better decisions regarding investments or participation within this sphere. As more people become aware of privacy tools and other innovations being developed within this space it will only help drive adoption forward.
We should always ensure our facts are readily available when engaging with others on these topics so they can make informed decisions too!
