Happy to oblige. I will have to skip a lot of reasoning and contingencies for brevity's sake, but I hope it gives you an idea of what a basic income might actually mean at least.

So first of all, a basic income would be a lot more transformative to society than it would seem at first glance. It's not just about people getting more money to spend. Crime would go down, peoples health would improve and we would trust each other much more since there's much less reason to lie and cheat just to get by (which is considered a major factor in the success of the Scandinavian model.) We'd need less police, less health care, and insurance costs would go down. And of course the entire means-testing bureaucracy would be unnecessary.

Then there's the labour market. Not being required to hold a job, and the increased bargaining power that entails, could lead to a number of different outcomes that are sometimes hard to predict. Shitty jobs would either become less shitty, pay better (which of course makes it more expensive for the employer), or get automated if it's cost-effective. As would jobs individually considered harmful, meaningless or counter-productive, like the military, weapons manufacturing, telemarkting and advertising, to name a few. People would likely get a lot more educated, and the education system would hopefully transform from being a production line of worker drones to actually encouraging curiosity and learning. Innovation would flourish, since anyone could just go out and do their own thing without risking homelessness. Cooperatives would be much more prevalent. "Good" jobs might pay less, since there would be a lot more well-educated labour available.

But here's the kicker: when having a job is no longer essential, there's no reason to artificially create jobs. We could stop encouraging consumerism and infinite growth, and institute policies that are untouchable today because they remove jobs or hinder job creation. Which would cause people to spend more time and energy on what they really want to do, things that actually matter, rather than hoarding stuff. Many would work less, others more, because they're able to do work they enjoy and don't have to do it primarily for material gains. Those with small children or elderly parents could spend more time taking care of them themselves, instead of shipping them off to some institution or other.

A lot of work that's good but difficult or impossible to monetize, that currently need to be supported by advertising or considered charity, could actually be done full-time without having to spend your time fundraising or degrading your work with advertisements. It could be done part-time alongside a part-time job for some extra spending money, or on a break from your ordinary job. I think we'd see a huge increase in political activism, journalism, and a transformation in how democracy would work in general. Finally, if we got rid of copyright, the production of creative works would be included in this category, and while not very likely, it would be possible to produce something like Game of Thrones without a single cent of funding.

If all that waste and abuse could be eliminated, or significantly reduced, it would reduce cost at every step of the production chain. Profit margins, and therefore prices, would be kept down unless for some reason competition decreases. Prices might even be lowered further if there's less manipulative marketing creating artificial demand. Skilled labour might be cheaper because there's more of it available, and if it's something people really want to work on I believe they'd care less about the paycheck and more about doing what the want to do.
