Most observers doubt it will make it that far. It needs unanimity among Democrats in the Senate, which it's unlikely to get.

This is more about nudging the Overton window, declaring that it's something they will consider seriously. They want people to see what such a bill could look like, and what would be in it, to see how they react.

It's possible that the Democrats will pick up a few Senate seats in 2022, making passage more feasible. If so, Biden's veto becomes relevant, but it's also subject to internal party negotiations. They could provide various ways to mitigate his concerns, or simply make clear that it would greatly improve the party's standing.

That's a problem for a couple of years from now, when things will be different. They're just laying the groundwork.
