the 5 points of architecture

i realised, upon reading abit of corbusier that the 5 points of architecture point to the pilotis.
what are the 5 points,
1) pilotis
2) free facade
3) free floor plan
4) ribbon windows
5) roof gardens

apart form the roof gardens, the other 3 points of architecture were possible because of the pilotis.
and this pilotis is birthed from his conception of the Dom-ino system back in 1914.

free facade, free floor plan, ribbon windows and roof gardens.

i guess in my precedence i would like to answer the question of why these 5 points?

i guess it could be summarised to 2 points.
the pilotis and roof gardens.
the other 3 points are the by products made possible because of the pilotis.

but looking on the reverse side, could there be a possibility that could load bearing walls still happen in a pilotis?
and the furthur question is whether there could be a new way of load bearing that could revolutionize how buildings are created and what are the new possibilities of that?
why i say this is because from the way i see it, architecture entered a new era ever since walls stopped become load bearing and pilotis or the dom-ino system came into being.
walls no longer determined the scale of the building.
with pilotis an infinite possibilities of buildlings in scales unachievable in the past become plausible.

my question now is there a more efficient way of load bearing that can be used to create buildings that defy gravity yet are perfectly sound engineering wise.

could buildings of massive scale be built in inverted l shapes?
imagine if buildings could be like trees which have planty of branches and not topple over.
the possiblity of opening up land space would be much greater. and the abundant space in the sky could be used.
just imagine an urban forest literally.

how about an inverted pyramid ? would such a structure be physically possible?

i believe that would lead architecture to the next level and heavily manipulate technology and pully systems of most intricate complexities.
steel cables would probably need to be thinner with the strength and flexibility of spider webs in relative strength.
new methods of reducing friction and materials of unbelievable hardness perhaps equivalent if not stronger than that of diamond would have to be utilised.

somehow, i feel this is not impossible.
i know i am not the first person to think of this idea.
i wonder if i'll live the day when this happens.
