Bitcoin is still better than most fiat currencies
It is indeed highly volatile, but its volatility is mostly to the upside anyway, and this is in stark contrast to fiat currencies which might in fact not be as volatile as Bitcoin itself but they all without exception go down in value (i.e. depreciate) in the long term. Apart from that, "temporary jobs" are what many businesses routinely deal with, i.e. they receive an order and fulfill it, then wait for the next order. Or don't wait but it doesn't change anything in respect to "temporary" nature of their job. Freelancing is pretty much the same. Strictly speaking, it is a sort of small business in its own right
I agree about how good is to deal with BTCs because the upside volatility. I like the temporary freelancing jobs too, the only negative effect is that we don't have guarantees and it can finish anytime, hard to live from this kind of activity. Today you can have a good job, earning in BTCs, but tomorrow they can tell you: we are finished now
As I said, it is the same with many businesses
But you don't need to be involved in just one project. If it requires you to spend most of your time, your work should be paid accordingly. In other words, you toil one month, and then you can live a year off doing basically nothing. Apart from that, many projects (if we talk about developing) need support anyway, so again you can lay yourself out for a certain period of time, and then live off that project providing support and consultancy. More such projects will make your life a lot easier
If the market goes well (if there are many jobs, economy working nice, money circulating), there will be always disponible jobs for everyone, since low skills based jobs until high skill based jobs, theoretically it can work very well.
I think your example about toil one month and then live a year off doing basically nothing applies better for high skilled jobs, paying more money, I know people that make movies, cinematographic area live this way, but for most people, they will need to work all year long to have a decent income and live well, as they don't have skills to apply to advanced jobs.
However it's not impossible for ordinary, biggest parcel of population people too, as they can save money and at some point an investment will be enough to receive a decent income and live more confortably by receiving passive income, and with the extra boost of the BTC price constantly increasing.
