This is a great explanation! One addition — decentralized applications are not only about censorship resistance — they are also about reliably committing yourself to a set of rules. For example the Bitcoin as a store of value (which you a bit neglected — but I believe it is quite important) is about committing to the issuance plan. Governments have no way to reliably commit themselves to a money emission plan for fiat money — and everybody believes them to cheat — this is probably the main reason why Bitcoin got so popular.

Another minor point: Lightning might improve efficiency — because Lightning is a hybrid centralized-decentralized system — it is about adding many centralized network onto a decentralized base system.

As about betting for or against cryptocurrencies — even if you believe in crypto — then still you never know which one will be the future king, and probably there won’t be more than a few that will survive.
