The keycaps are a part of this keyboard’s cost (Keebio prices a similar set that comes with Cepstrum at $52), though it’s not easy to find choc-spaced keycaps for cheap unless you 3d-print them.

The primary drivers for the cost are likely the R&D work behind the keyboard and that it’s a keywell (with more complicated assembly process).

Perhaps you could get a used one - IIRC there was a channel on MoErgo’s discord.

If you mean the thing for strafing, there was a QMK pull request, though this is now being hastily banned from just about every competitive game. If you mean hall effect switches, I’m not aware of any keywell keyboards with them - there’s just a single 58-key (Lucca 58-HE) as far as column-staggered boards go.

If the keyboard would be sitting on your office desk anyway, you could get yourself an Ergodox/Redox/ErgoDash and not worry about shedding keys for sake of portability.
