25 NL people will still throw out a Cbet without a hand, at least some will. Some will also give up once they are called.

granted, disguising your hand is less important at 25NL than at 100 NL, but it can still have some merit.

there are some players at 25NL who are trying to play "correctly", and that usually means folding too often, taking 1 stab and then giving up. Not calling with A or K high.

a side benefit of floating is it tends to make some players adjust their game out of their comfort zone, which leads them into even larger mistakes than they usually make.

just about any play can be profitable given the right situation.
