Why are we still using discs instead of cartridges?

Depends on the cartridge. 3DS cartridges sure, but I don't think you could carry many N64 cartridges in your pocket

No idea how big ones for current home consoles games would have to be though, so maybe it would work it.

Current home console games would fit on SD cards. Such cards can already hold up to 128GB while current home console games are shipped on 25/50GB blu-rays.

And I believe the Wii U discs could hold up to like 50 gb and the only game that actualy came close to filling that was Xenoblade X I think.
