Ground stop at JFK due to staffing

My concern is that we will end up in a state of perpetual government "shutdown". The republicans, instead of reopening the entire government, will simply choose agencies to fund in order to keep the pain felt by the American people just low enough so they don't get fired (ala office space).

Once that happens, Congress has basically iced itself out. Oversight from unfriendly government agencies? No worries, they're shut down because they're unpaid. And clearly this demonstrates the executive needs more power, since Congress is completely frozen. Finally, the Supreme Court is no longer an issue either, since that's not funded either.

Someone tell me why this couldn't happen.

Yes.

As the majority, the Republicans in the Senate can unilaterally eliminate the filibuster rule, then pass anything they like. They don't need Democrats' votes at all. Republicans have already done this in the past when they wanted to ram through a bunch of judicial appointments and again when they wanted to get several Supreme Court justices through without any Democrat support.

The only thing stopping them is that the Republican party wants this shutdown to happen. It gives them another example to point to when they want to claim that government never works, license to harm government workers they don't like, an easy way to have government workers leave on their own, an excuse to fire government workers they want to get rid of, and another thing to blame on Democrats (because their base doesn't know any better).
