Maybe a crisis will occur and maybe our descendants will have to make a tough choice, but that could enrich the story of the performance. If they choose to end the performance for whatever reason, that’s their business. The hopes and desires of one generation can only hold sway over the next for so long.

Well, in this case, "you can already buy a ticket to the finale, so your distant descendants can go see it." Selling tickets for an event that far in the future makes it the business of the ticket purchaser and whoever they leave the tickets for.
Is the money collected from the tickets being held in such a way that it can be refunded if/when this project fails before another 600 years have gone by? If not, it seems like a potential scam in that sense.
