I don't see a reason why all of those new and old venues can't be accommodated in some way. One simple way of doing this is to hold a race at some tracks only every other year or so. A lot of governments are willing to sponsor the F1 race because holding F1 race is akin holding Olympic games in terms of national prestige. However, the Olympic games last only two weeks and often won't return for 50 years. The F1 weekend lasts 3 days but could easily return every other year or every two years if there is enough interest. This arrangement could be problematic if the race track was built by investors who are anxious to recoup their investment. Those could be accommodated with a contract agreement that gives them a race every year for say five years, and then an option to hold the events less frequently.
