Philosophy is metaphysics. If we don't understand metaphysics then we don't understand philosophy. If we don't have the foundation in place we can only build sand-castles. I feel you are misunderstanding both metaphysics and philosophy, You can complain about both but you can't separate them and endorse just one.
I decided to create new topic because of interesting thing that troubles me. My experience gives me hint that building sand-castles is the only thing that humans do and matters to them. And it is not good or bad, it is ok, it is fun.
The first question. Why do we need any foundations at all? Does it not depend on human to have or not to have them? Is it not possible to live without them?
Better to say a starting point is needed for human, as he can choose and change its position.
Wikipedia says that metaphysics tries to answer some questions like:
What is there?
And what is it like?
But I personally cannot give any answer to those questions. They make no sense to me. I do not know what is there. For example, I see myself as:
- some thing of many little things that is grouped together by some pattern ( cells, molecules, other elementary particles, waves, electric currents, transfer of energy, etc.)
- member of society
- member of subsociety1, subsociety2, subsociety3, etc.
I reason that there is "something" out there. "Something" is interpreted by my mind with labels it has. Philosophy helps to create new labels. Philosophy gives methodology how to create new framework of thinking, arranging and rearranging labels.
The second question. Instead of asking what is there maybe it is better to ask what we can do with those "lego bricks" we feel by our senses? And instead of what is it like maybe it is better to ask if we humans have limits on inventing things?
