You can move items around the world with Packing Tape Mod (1.19.3, 1.18.2). You can easily pack a large chest of items and move it from one location to the next.
The following TEs are blacklisted by default:
- Command Blocks: Security concern: moving command blocks may allow things to happen that shouldn’t happen.
- End Portal blocks: Security/gameplay concern: Moving end portal blocks could cause issues.
- Mob Spawners: Balance concern: moving block spawners can be cheaty and should be reserved for hard-to-obtain methods.
- Player Skulls: They don’t have an ItemBlock form, and can be moved away easily regardless, so no point.
- Banners, Comparators, Daylight sensors, Pistons, Note blocks, Signs: No point in packing them (except the sign, which also be a security concern).
