yeah its done to incentivise people to maintain full nodes
Incentives to maintain full nodes
This system introduces powerful incentives to maintain full nodes. Many people argue that the lack of an incentive to maintain a full node is a problem in the bitcoin system.
1) a steady flow of txns will generate some fees even if all public keys remain active. Active keys must be maintaining full nodes. Otherwise they could not provide the voluntary signatures which prove their activity. Even very weak incentives are sufficient in this case. If almost all keys are associated with active nodes, then it is not necessary to motivate additional participation.
2) Some public keys may decide to become inactive. This is costly for them. They will suffer a loss of 5% of their balance per year for as long as they remain inactive.
3) The active public keys constantly capture revenue from inactive public keys. This means that the incentives to remain increase dramatically as participation falls. Suppose that 50% of public keys maintain full nodes, then this 50% will capture 2.5% of coins per annum. This is equal to an annual of return of 2.0%. The alternative, inactivity, yields an annual return of -5.0% as discussed in point 2. I consider this a reasonable incentive level and participation rate. Suppose that I am wrong, and only 10% of public keys maintain full nodes. Then these 10% will capture 4.5% of all extant coins per annum. This implies an annual return on participation equal to 45% per annum. This is a very strong incentive and is almost certain to be sufficient, even if nodes are quite costly to maintain. If only 1% of coins participate, then 4.95% of all extant coins will be distributed to this 1% each year. This implies a weekly return on participation of 3%, a pirate ponzi scheme level return. If these incentive are inadequate to support a healthy network of full nodes (which seems unlikely to me), then the levy on dead coins could be increased to exceed 5% per annum.
4) Many people will not have enough coins to justify running their own node. Such individuals will likely use an online banking service which could store their limited spend key. The service could return interest to users in exchange for managing their keys.
5) Other individuals may prefer the privacy associated with dropping out of participation. These individuals are still welcome to use the network, but must face a wealth tax of 5% per annum to compensate for the security risk created by their behavior.

You mean the extra coins are only divided among the people that are active with PoS? So 20% extra coins in the first year gets divided among the people that are still active? I thought it was just 20% extra coins for the active part of the network.
