The thing I don't understand from your perspective is: why can't we have all solutions? Do you like dynamical block size? If yes, you don't have to mess with Bitcoin, there's Monero. Are you willing to trade scalability with protocol privacy? The answer is again, Monero. Do you want better scalability and decent levels of privacy? Litecoin. Do you not care about having a hard cap? There's a host variety of altcoins to choose.

Bitcoin has clearly charted another course. Its aim is not simply to facilitate transactions on the main layer but to enhance its role as a medium of exchange in second layers, while striving to become the cornerstone of honest and true money. Its most compelling feature is its finite supply, which is sustainable through sufficient transaction competition on the main layer.
