I don't know the context of the quote and I know next to nothing about CS Lewis, but having blown my life up at one point and experienced freedom on a level few on this planet could achieve (health, money, time, and will) the quote rang very true for me.
I think some people grow up in a community and are rooted within that community, but those people are also subject to that community and there is no guarantee that that "community that surrounds you with love" is a good community.
"Always be surrounded by love..." unless you are gay. Gay, trans, atheist, feminist, brown, an opioid addict, a questioner of authority, or otherwise different.
It's not uncommon for members of the trans community to recommend cutting off family members for acts as minor as accidental misgendering, while ignoring the very real harms of social isolation.
As a trans person who's lived in a multi-generational household where only one other member knew I was trans. I can personally attest that even being closeted can be a good tradeoff for many people.
Obviously in cases of violent queerphobia the calculus will be different, but I think people chronically underweigh community and make their own lives worse for it.
There's a reason for the modern resurgence of communes, and it's not just rent. After decades of increasing social isolation we're finally coming back to the realisation that we're social monkeys.
