List of the things one cannot buy in the tiny country named Luxembourg

So while sitting at this very nice hipster-like cafe in the city centre and observing people for more than an hour, I have started making this list of the things one cannot buy in Luxembourg, where minimum salary is 2,000 euro and people are all about the money.
I guess, as I am such an idealistic, but not materialistic person, it was pretty unrational and on a half way I thought that maybe I need to change it into the list of things you can buy... However, I am not someone who gives up easily, so here it goes:
kindness
brain
smart ass sense of humor
time
long walks
good weather
short walks
good genes, and I know, it sounds like jeans, but this one has more DNR and less of cotton in it.
laugh
rain
stars
wildness
moon
food made with love
late night talks (unless you call the hot line... but hey... this we dont count.)
kidneys
lungs
thyroid gland
(well, of these three I am still not sure as I do not have that much of connections).
heart beat
oxygen
happiness
giraffe and a jet
(because giraffee would just not fit and jet is too expensive).

I know, it is large, but wait, I am just starting...
