If I invest the majority of (electrical) energy and hashing power, how is it fair that I dont get the majority of the reward?
You will get enough fees to cover those costs, and still make a profit. What more do you need?
I assume here that the blockreward is still higher than the tx fee reward.
Please read my idea more careful, because it explicitly states it will be equal (or less).
Those who put their time and money into this make it what it is, yet you want to punish them?
They will only be punished if you compare this hypothetical coin to how Bitcoin works. But Bitcoin punishes a much larger group: the actual users, people without mining rigs. They also invest their time and effort (for example in promoting it), you want to punish them?
I think you have a very problematic understanding of "fair".
My view of fair is random distribution among the largest group of people, while still letting miners make a profit. Yours (as a miner) might be a bit different, thats no surprise.
