Capybara
Encountering a capybara requires either South American travel or a visit to one of numerous zoos and wildlife parks maintaining captive populations. Certain regions permit capybara ownership as exotic pets, though their social requirements and semi-aquatic needs create significant care challenges. The average person can reasonably expect to interact with a capybara within their lifetime, whether through tourism, wildlife encounters, or internet imagery. The capybara remains fundamentally accessible to human experience.
Rocket
For most of human history, rockets existed entirely beyond personal access. However, the emerging space tourism industry has begun democratising rocket travel, albeit at costs exceeding $450,000 per seat on Virgin Galactic and substantially more for orbital flights. Approximately 600 humans have travelled to space in total. The rocket represents humanity's collective achievement, yet remains individually inaccessible to virtually all people. Nevertheless, anyone may observe rocket launches, creating a vicarious accessibility through technological spectacle.
