The idea is that because you are locked in your Cuffs, you should be deprived of the convenience of touching faraway things (over 1.5m away from your avie's centre point) at will. After all, you are locked in your Cuffs!
This can be changed in your Cuff Menu (/1c or touch any cuff):
Cuff Menu > other… > RLV options > notcouch.
As this is an RLV option, only your Owner can change it.
