The is no rich list, it's not because someone doesn't want to put it together. Ring signatures cause blockchain analysis resistance. What this translates to with a rich list is that the value of any particular transaction seen on the blockchain is very likely inaccurate. A transaction of 10 could look like a transaction of 100 or a different value or whatever. It's just how it works, and was designed that way.

As far as the number of wallets on the network, that also cannot be observed by parsing the blockchain. With stealth addressing/one time addresses, it's virtually improbable to describe an accurate number of people using the software. The best statistics for something like that can be found by tracking the number of binary downloads from a couple of different locations. That won't give a perfect picture either though.
