I am surprised to see the list of physically backed ETFs but unfortunately none of them are approved till date which is a matter of concern.
Why are you surprised by the fact that no ETF has yet been approved in the US, no matter what type it is? There is a time for everything, and the SEC believes that the time has not yet come for this form of trading - for reasons that have already been listed countless times in dozens of threads on this topic.
Does SEC have any issues with physically backed ETFs? Even in 2020, they had rejected quite a few physically backed ETFs.
Obviously, they have problems with any type of crypto ETF, which is why they havent approved any yet - isnt that self-explanatory? If you are interested in the exact reasons why a crypto ETF was rejected, simply read what the SEC wrote in its reasoning.
Here is something direct from the SEC Commissioner about the reasons and opinions when it comes to the BTC ETF ->
