banks were crap in 2009, nowadays they are fast as hell even when it comes to interbanking transfers, they were also expensive yet they dropped the fees, while...eh, I feel like we're going backward.
A centralized network can scale vertically, easily. A decentralized network is very different. In Bitcoin, it's more like "we've taken a different path" rather than "we've stuck" or "we're going backwards".
So let's compare it with the most expensive and costliest system on the planet and ignore that its relative just 100 lines of codes different can do it for
Avg. Transaction Fee 0.275 DOGE ($0.04).
As I said, things evolve, and you can't evolve if your target is to beat the slowest guy, this is not like running from a bear!
I can't help but notice that you keep repeating the same argument about Dogecoin. Dogecoin does not have a hard cap. There will always be a subsidy, and therefore, transaction fees do not
have to be high. In here it's different.
You're somehow expecting a network with a hard cap to have low transaction fees, and be completely dependent on-chain. That's only possible with gigabytes of block size, and the assumption that the demand for on-chain transactions will skyrocket accordingly, for if it won't, the system's days are numbered. In any other case, you can always argue that the system is not as cheap as custodial solutions.
