There is no perfect system and that same thing with absolutism. Absolute decentralized is not effective nor absolute centralized system. Therefore a combination of both system should do in order to get an effective and efficient system.
1. The lack of authority from the crypto founder to resolve issues from its user.
i don't know how you tend to view this @OP but you don't expect a two distinct or directly contradicting view to work together, its like asking the democrats and the republican parries in the US political system to work together. decentralization is one of the bases of the stability of the cryptosphere. Tts a building block that shouldn't be tampered with. Bringing centralization into any aspect of it is as well trying to break its stability and i don't see how that helps. Besides, centralizatio9n has its own problems and their would be a lot of influence on the system. Decentralization may not be perfect and bringing in some elements of centralization doesn't or isn't going to make it perfect either. If we are to face the fact, its the decentralized nature of cryptocurrency that makes it enjoyable and a major attractant. Having freewill is everything, so long as what originates from your end has little or no effect on the other user. mistakes are allowed, it's a common human nature but, when you make them, you learn from them. its all part of the exercise.
2. Miners service are decentralize.
Who would ever thought that they could get you a 1$ transaction of a fee which could be more than a thousand dollar's fee? There is something wrong and miners should be held liable into this by only limiting the transaction fee to be deducted not more than the transacted amount. They are abusing due to the fact that their service is in demand especially the bullish trend of bitcoin.
To the best of my knowledge, fees aren't determined by miners, its based on the congestion of the system. its based on a complex algorithm set up to control the rate at which transactions are been placed and in turn determine how much activities could be done and time.
