But naive in a way that most people (?) would like the world to be.
But ultimately, unfortunately, unrealistic.
Building has always been the kind of difficult that, had you known at the beginning then maybe you wouldn't have started. And still quickly and easily destroyed.
Keep creating and building, otherwise there's nothing else to do. Love the obstacles for challenge of defeating them, don't hate them for their existence. To build X you often have to build A, B, and C (and sometimes all the rest of the alphabet) just to have the right setup to maximise the success of X. It can grind, but focus on the benefits of X.
Which sounds like the position they've taken, thankfully.
(Where X represents "anything" and is specifically not the <whatever it's classified as> platform formally known as Twitter).
The melancholy will return, just ride it out each time. It gets easier, gradually.
