While it's true that travel has become more common and often necessary in modern life, I wouldn't say it's strictly "impossible" without traveling. Many aspects of modern life can be navigated without physical travel, especially with the rise of remote work, virtual meetings, online education, and digital entertainment options. However, travel does play an important role in many people's lives and careers for purposes like business, tourism, education, and family visits. But for some individuals or lifestyles, it may indeed be possible to manage without personal travel if desired. The necessity varies greatly depending on one's circumstances and goals.
