ELI5: If faster than light travel may theoretically be possible because the universe is expanding, isn’t that relative to your origin, rather than your destination, which is also moving? Ergo, you aren’t getting there any more quickly…
And wouldn’t light then also be travelling “faster than light”?

Every observer regardless of frame observes that the expansion is faster than c. > And wouldn’t light then also be travelling “faster than light”? Space on light's path also inflates, so in terms of units of space travelled per unit of time nothing changes.
