I think lego is reaching levels of absurdity that I didn't know were possible. I get that you have to target another demographic with prices like these, but I'd love to hear why. Does no kid play with lego anymore? Are these prices justified or are they now a luxury type of brand for collectors? What is the deal with lego these days?
You seem to be missing some critical context, which is that this set is coming from a site where fans can just propose new sets and if they get enough votes LEGO will consider making an official version. So yes, this is largely a set for adults and the price is set as such.
