...and this is why Peercoin, as a proof-of-stake system doesn't depend on centralized mining. It only used proof of work for fair distribution.
Peercoin is still in its distribution phase and is still cheap. It is basically where Bitcoin was in 2011 or 2012 before the ALTcoin rush, where it was just easier to create your own coin (like Eth, Steem, BTS, ZCash, etc) than it was to pay attention to key core currencies like Bitcoin or Peercoin.
In our rush we're not paying attention to what you've just pointed out.
4 Years ago when Sunny King launched Peercoin he knew we'd be having discussions exactly like this before most people realized it would be a significant problem. He was right.
