Theoretically it's the case but we all know that it's not realistic in countries like Srilanka. Opposition would rally against each n everything regardless whether it is deemed good or bad. Hence if we wanted GOTA to implement and do what he said he would do, the only logical decision is to give him the power that he wants to do it.
If we didn't make it real we will be forever in the same place
Gota does not have any power over the parliament, even 2/3 majority could overpower executive branch too. Specially with 19th amendment (which was voted by 215/225) has removed some powers and even there could be new amendment which could remove further. Its all depend who is gonna contest 2025 presidential election
If its gonna be namal, 2/3 might even restore power
