Yes, but universal basic income instead of universal healthcare has two issues as well:
You may not be able to afford expensive healthcare procedures, which may result in all ranges of bad consequences, from lost productivity to death. In either case, there's a big chance society loses a productive worker for no good reason, and for the person who couldn't get healthcare it's obviously super bad, too. All while this expense would be returned in the economy many times over if the person got recovered and continued working, and the person in question could keep living a fulfilling life.
Relying on private healthcare institutions means falling victim to the price-inefficient businesses, as a lot of your money goes to cover profits of the healthcare organization. When there is no public alternative, prices go through the roof. Even in the US, where there is some government oversight but no full-scale universal healthcare system, the prices for healthcare are insane. Thereby, you either have to hand people a fat UBI check and constantly increase it as companies drive up their appetites, putting more strain on the system than universal healthcare ever could, or let people not have decent healthcare, or control the healthcare institutions (which is not super libertarian), all while living with a reality that many people will not think of their medical needs or will genuinely have other strong priorities and will put money to something else, ending up shooting themselves - and the economy - in the foot.
I often hear criticisms of some "committee" deciding whether you're gonna get healthcare or not, like here. In an alternative when it is ruled by money, it's how much you earn that decides it. Someone in a critical condition might not receive help simply because they are poor. Someone will always be cut off, and it'd better be someone who needs the help the least or requires too much resources to help that could be better spent saving more people.
This is constantly ommitted by the haters of planned systems, which I think is very unjust.
Cryptocurrency is a useful technology that has some real-world use cases - for example, living in Russia, I use it to circumvent sanctions to donate to some of the crypto-friendly creators, pay for a VPS abroad, and I keep calm knowing I can transfer money to my relatives abroad.
However, it is obviously not the answer to how we should build the financial system. The problem is not environment, actually - many Proof-of-Stake blockchains allow to transfer crypto with minimal environmental impact - but the poor on-chain regulation (including taxation, too) and potentially excessive infrastructure, as well as little protections against malicious and fraudulent actors.
Besides, inability to control emission, while helping maintain the value of the currency over the long run, also means that many interventions that can save economy in a crisis are simply not available. And a deflationary nature is known to cause bubbles.
I think the point is, unlike buses with fixed routes, such shuttles could deliver people to places that face temporary massive traffic - like concert venues or whatnot.
There is no need to constantly run huge amounts of buses there, but at some point of time there's a lot of people willing to go - and such shuttles, flexible in their routes, may be the solution.
Long story short if I remember the video well after watching it a while ago: while sand is cheap for thermal energy storage, storing it with reasonable efficiency requires a massive unit (much higher capacity than one home would reasonably need; can't be scaled down well) held underground (immediately incurring massive costs).
