This is an interesting question, and one that has had many of us arguing with each other through the years.
>Does it mean there is still no market, so to speak ?
There is a market, but one that is not based around traditional exchange of object = cash, alone - some is, but of it is not.
I know that many on here have their own 'real' examples...
I can also give you actual examples of artworks that I know have been either commissioned, bought or on loan to different institutions and private individuals, but busy with doing things at the moment.
Here are some links that I quickly thought of that may help a little bit more.
wishing you well.

"At the beginning of April, a debate took place on rhizome.org
