In that case, why would anyone mine when there are no transactions?
Not many will, and having that level of computational power at that point would not be needed when that young. As RLC grows in adoption with goods/services sold/bought/traded the network will need greater mining based protection and processing... it's actually not that bad of a model, and there is no worries like in BTC when generate rates halve, this is 100% tx fee at the front so all you should see is slow growth as tx quantities increase assisting in paying for more mining in the network.
"that level of computational power" will never be needed. It is a centralized system just like ScamCoin. Mining is just window dressing to obfuscate the fact that the coin only exists because of the central authority. There is no reason all transaction processing can't be done by a single server.
