I'm a greedy miner too. Miners have it easy for the next 6 years, there after if they charge high fees they devalue the network if the value of the network drops the status quo change if they don't adapt it degrades it will keep changing until the status quo brings new actors.
It's actually greed that will prevent degeneration, miners who scoop up the transaction fees that are equal to the marginal cost will out compete there competitors. At every halving there will be a disruption and miners will start a new competitive race to discover the marginal cost of business.
SC running on the Bitcoin protocol using SPV proofs change this incentive, this is why I'm skeptical.
I don't have the answers but again this is one concern of mine, I would be able to afford the transaction fees and utilize the network but of course their will be times that a internal wallet service like Coinbase will be used just for convenience.
I am worried about someone like this being able to use
BTC in the future without a service like this -

immigrating to this new world will be hard, there are hostile tribes and wild animals with skeletons that look like dragons.
weather we get there on the Bitcoin boat is still not guaranteed.
but we plug along concerns and all. I dont know but I've bought a ticket.
