Moments before spontaneously combusting Frank at
was heard opining:

There's soil under the floor
where I want to put it (large dining-room) so jacks aren't going to
work to support the floor unless concrete footers of some kind are
laid... too much expense and it's only a crawl space. ........

The ground in your crawl space doesn't freeze does it?

No, but the soil is damp and soft and sinks easily.

Just put a
concrete patio block on the ground and shore up from there.

The block would slowly sink into the earth. That's what's happening to one
of our outbuildings now. One end is on rock and the other on soil and the
blocks sank.... we're going to have to have that fixed and soon.

If the
ground doesn't freeze, it won't move up and down - no need for a
footing.............

The supports under our house are set on vary large concrete pads that go
into the soil several feet because the soil here doesn't support anything
when it's damp. A block on the surface today will be sunk an inch by this
time next year if there's weight on it. :-( It's a clay soil that's like
mush when wet and like cement when dry. Our foundation blocks sit on a
wider foundation that goes down several feet. So far there's been no cracks
in the foundation, a common occurrence here. We have extra supports under
the sun-fishroom floor to bear more weight than an average floor but didn't
do that throughout out the rest of the house.
