This guy isn’t making a neat distinction between money and wealth like you are. Usury involves the lending of money at interest, and money isn’t exactly wealth. Land and capital is not money, but it is wealth. But we often measure wealth in terms of monetary value and this is what the guy is doing here.

People do things like invest money in projects or businesses in order to acquire more money and wealth. If they have land and use it wisely  they can generate a nice revenue stream and improve the monetary value of that land.

This guy just flatly stated that using wealth to make more wealth is wrong. He doesn’t distinguish in any way regarding how this is done, just makes a blanket condemnation. 

 It's a 4chan post that drives at the gist of the issue, it can only go so far. Given the obvious context of the post, I think it's rather pedantic to quibble on how the anon uses the term "wealth."
