It was quite easy to imagine great uses for the internet, but they sounded pie in the sky - until they weren't. It's a similar issue with crypto. Being able to rapidly send or receive money anywhere in the world to anybody with a computer, independent of any third party, is itself already an absolutely amazing possibility. The only thing missing is largely what was missing from the internet for decades - large scale adoption for utility.
One major difference here is that the grand vision for the internet stood to help governments in many ways, whereas cryptocurrency stands to weaken governments in many ways. Currency controls enables nation to try to tune their own local economies, control international trade rates, go infinitely far into debt, and can also work as a great weapon against enemy nations. Widescale cryptocurrency adoption would stand to shatter all of this, and that's something no major government is going to just idly allow to happen.
I would also add that in the zeitgeist of the world today, the internet would likely have taken far longer to materialize than it did in the past, for reasons analogous to those with crypto. Can you imagine the US's response to digitally interlinking with China or Russia? For that matter China or Russia's view on the same. We live in a brave new world where each nation wants to strictly control their messaging while limiting, or eliminating, outside views. The internet works to undermine all of that.
You do not need a third party - that's one of the many great things about this. You can go download (or compile, or make) software right now to generate a completely functioning Bitcoin wallet that you can then send/receive coins from.
