The only (and most important) obstacle for these hypothetical cartridges would be their production costs. Otherwise, they could very well be superior. No scratches, no install times, faster and more quiet data-reading, etc.
Perhaps dev based carts could be made to cut the cost? (32GB carts for devs with around 32GB games, 64GB for the bigger ones, etc).
