Why not just sit it on the ground and buy a taller tank? Pressure is a
factor of the "head" (height of water above the tap), assuming you've
used at least 1/2" pipe and not a long run.

Best to ask those who sit tanks on stands. But a tank sitting on the
ground right outside your window can block a lot of view. If yard space
is at a premium, a water tank on a high stand can still allow you to see
out, and it will not block cooling breeze from that direction. Security
would come into it, too, you may not want a tank to block your line of
sight to the garage, street, neighbours, etc., or to offer cover to some
one trying to break in. Where the stand already exists, it might have a
garden or storage shed underneath. Some farm tanks have a gravity fed
shower underneath or alongside.

Filling a high tank from a well or an underground cement tank might be
preferred as a fire safety measure, offering a supply of low-pressure
water even should the electricity fail.

But a high tank means that you
are not held hostage to a pressure pump for gardening, and a reliable
240 supply during hosing down during bushfire weather.

Reliable mains and bushfires do not go together.

Which is why I didn't mention mains.
