The OP's question conflates two issues that must be separated.
Firstly, is it worth spending that kind of money on a hifi source component? If your answer to this question is "no", then you need go no further.
Secondly, is there some extra benefit to be gained from vinyl over other formats? Having tried to live without a turntable for nearly five years, I have found that it does give something more. For whatever reason, I find it generally a more enjoyable listen, particularly over extended periods of time and mastering notwithstanding.
That's all that matters to me. All the technical and ideological discussios so far are irrelevant.
