what if a 1:1 scale replica of any of the large habitations from sarasvati civilisation uncovered by ASI, is built in and around current urban centres ?
it will help the public understand the scale, instead of having to visualise from what they read from a few sentences of their books or internet.
since it was made of mostly brick and traditional materials which are still used, it shouldn't cost much by today's standards.
archaeologists will have a chance apply in real word the practicality aspect of their scientific assumptions and also ponder on aspects they haven't yet applied their mind on. to build something, practicality is essential, it's no longer a theoretical discussion.
