Advocating for the government to just take something without due process in any circumstance is stupid, and permitting the government to ignore our rights at its discretion is stupid.
Pitch it differently to include things that are already inherent and explicitly written in a document that preserves our rights, and of which civil asset forfeiture clearly violates? Why would you sit around floating along the idea of keeping our rights instead of just outright demanding it? No shit things like "the assumption of innocence until proven guilty" are hard to argue against -- because no law is supposed to exist that violates the due process through which this assumption is rooted. If they went ahead and ignored various other "inconvenient" rights and freedoms, do you think that would be acceptable to go on at all -- or at length as you permit in this instance? We could go ahead and let them pass some more laws to go ahead and re-institute slavery and no longer allow the public to vote. No need to worry, though, they'd never actually do anything with those laws because, hey, we can trust them to be responsible!
Our sides are nowhere near the same. A law currently exists that so obviously usurps due process that it is indefensible. I happen to like having rights and freedoms, you don't seem to feel preserving them is of any consequence.
