People can buy XRP using proof of work based coins, including bitcoins. So those who want to spend proof of work to obtain them are free to do so.
The problem is that you advocating proof of work along side central distribution of XRP, while I am advocating proof of work
in lieu of central distribution.
No, remember I also said once we get the source code we can make a fork, divide all the RIpples evenly between all the people who claim to have thought of a more fair distribution method, and let them all apply their method to their share.

For the record: I have thought of a more fair distribution method, whereby I will receive all the coins and spend them on goods and services in the Ripple economy.
