Is it ethically acceptable, from a utilitarian viewpoint, for me to spend many hundreds of dollars to attend Manifest?

Prediction market on manifold. Approximate Manifest tickets/travel/accommodation costs: https://www.havenbookings.space/festival-season Manifest Ticket - $538 Manifest Supporter Ticket - $3000 Manifest Student Ticket - $350 Manifest Volunteer Ticket - $100 Microsoft Bing Travel [image]https://www.manifest.is/ Where should I stay? Lighthaven can accommodate ~half of the attendees starting at around $100 per night. A link will be shared on this site and announced in Discord once booking opens. Alternatively, attendees organise affordable house shares in Discord, see #travel-planning. Can I apply for housing or travel subsidy? Unfortunately, Manifest is unable to provide support to those seeking assistance with travel costs. Booking.com: Hotels in Berkeley.
