You give a damn about speech. You're publicly criticizing the foundational document of a government, and calling that government a failure. That open criticism is necessary for change to happen and, in the United States, the constitution forbids the government from removing that criticism or punishing you for it.
The constitution is intentionally more difficult to amend than an ordinary law. The entire point is that the government cannot easily remove restrictions on itself. It's not an appropriate place to put, say, housing or employment laws, which should be ordinary laws so they can keep up with a complex and rapidly changing world. It's also not an appropriate place to put a statement that housing is important or that there is a right to housing, because such a statement is unenforceable and would need a separate law designed to enforce that right. There are plenty of countries with a "constitutional right to housing" that still have homelessness because it's such a difficult issue to solve.
Throwing a constitution out and starting over would be even more difficult than amending it and would lose what's already in it. Maybe we need an amendment ending prison labor and private prisons. Maybe we need an amendment extending more rights to immigrants. That doesn't mean that the constitution as it already exists is invalid and worthless.
