The literature dealing with rationalized parliamentary government frequently discusses mechanisms to ensure that dissolution or prorogation happens only with the approval of elected members. It exists in various countries that have a parliamentary, non-presidential regime or, at the very least, a parliamentary or semi-presidential regime.
The problem is that we tend to compare ourselves to the presidential system, which has a strong separation of powers, such as in the United States, for example, which has an elected president and an executive that derives all of its legitimacy from a vote. The president is not elected directly but by the electoral college. There is a risk in trying to import concepts from the systems of other countries with whom we may share a common language but not any institutional similarities. As far as those institutional similarities go, British parliamentarism may be a lot closer to other forms of parliamentary government, such as Germany's, than ours is to that of the United States.
