I think you have this correct too: you can only use the bitcoin ledger if you own bitcoin.

Therefor, bitcoin is an indispensable means to a valued end.

Josh doesn't know where Bitcoin gets its value

Perhaps I have oversimplified his second point. 

People probably don't just enjoy holding dollars. They like what dollars can get them. In that sense dollars are just a means. 

However, there are also some things only dollars can get you (you can only pay US tax obligations in dollars). 

So dollars have an end for Josh. 

Lawyers may be a means to a lot of things, but there are some things you can only get if you hire them. 

I have a feeling Josh does not count bitcoin's censorship resistance as an end.
