Your problems are twofold.
1. You think libertarian is a synonym for conservative,
2. You believe that now that leftist voices don't drown out all others, that Slashdot is now a "conservative echo chamber." This is the response of people who are not used to having their ideas challenged.
Slashdot has always leaned left. Now it's centrist. And that bothers you. Ars Technica is leaning further left these days, so go hang there. They have a user moderation system that's dumber than Slashdot's, but at least you won't get the banhammer for irking any of the hired moderators on the articles anymore.
Indeed. This system is a fraud that only replaces multiple welfare programs with cold, hard cash. It might reduce costs of administration, but it isn't basic income.
I would like to see a basic income program that truly pays everyone, but with the ability for those who don't need it to opt out. Let's see the wealthy progressives literally put their money where their mouths are.
This is clearly need-based in thinking.
If one person can get by on $X, it doesn't mean two people need $X*2. Housing is normally the greatest cost to a household. My rent or mortgage has always been my biggest bill, even when I lived in a dump in the 1990s. I had a new car, and the rent was still double the car payment.
If you look in the FEMA site, they say that they provide gramts to perform repairs not covered by insurance. And no, they don't do a needs test. Now, the typical rich person does not let their insurance lapse just so that they can get a FEMA grant. Because such a grant is no sure thing. They also point out that SBA loans are the main source of assistance following a disaster. You get a break on interest, but you have to pay them back.
What you are observing is economics. As a city or town population grows, the best land becomes unavailable and those who arrive later or have less funds available must settle for less desirable land. Thus many cities have been extended using landfill which liquifies as the San Francisco Marina District did in the 1989 Loma Prieta earthquake, or floods. Risks may not be disclosed by developers, or may be discounted by authorities as the risks of global warming are today.
Efforts to protect people who might otherwise buy such land or to mitigate the risks are often labeled as government over-reach or nanny state.
Oh, of course they were caused by misguided engineering efforts. Everything from the Army Corps of Engineers to Smoky Bear goes under that heading. The most basic problem is the fact that we locate cities next to resources and transportation, which means water, without realizing where the 400-year flood plane is. Etc. We have learned something since then.
Our problem, today, is fixing these things. Which is blocked by folks who don't believe in anthropogenic climate change, or even cause and effect at all. They don't, for the most part, register Democratic.
The problem with your explanation is that it's fact-based, and stands on good science. This is the post-truth era. Thus, the counter to your argument will be:
Evolution is a million line computer program falling into place by accident.
