this lower number is good and many will create at least one node this way we will be best decentralized system
It is a fair statement, compared to other currencies. Where big investors (early buyers) own multiple nodes and maintain them within one provider (server). That doesn't add up much to the decentralization and most of network may get offline due to a hardware failure of single VPS provider.
ZEN approach is different. If someone feels like having little profit - run more nodes, simple as that. More maintenance costs will be covered by better distribution and security of separated wallets. (Easier to hack one node with 1000 coins, compared to 20 nodes of 43 coins)!
