I like your post because it deals with real life issues. I like that you address homelessness-- which is something I've dealt with and is something I could (and likely will) experience again, mostly out of my own choice. In the sense that you describe, by failing to prepare adequately for potentially knowable eventualities and because I choose to have some form of freedom and independence, rather than live with parents, friends or work a job I hate in a town that bores me.
As for the cryptocurrency aspect, I definitely beg to differ. While I get the aspect about there being no checks and balances, to an extent, there's another side. The checks and balances we have in the old system are weighted in favor of the elite and big money interests. At least in crypto, anyone can make wise investment choices. In stocks, you need at least $20k in your account and a net worth over $100k to be an accredited investor and be allowed to day-trade. Is this helping people with low means? No.
With crypto, you can start trading (provided you find an exchange that isn't already being attacked by the old regulators) and day trade with $10 or $50 or whatever.
With crypto, long term HODLers have turned $500 into $100k (I'm not one of them).
I like that you referenced Scripture, but we can see the interpretation differently. I also think the world of decentralized systems and assets will bring about a new kind of prosperity where less regulation will actually create more options for those who would be facing potential homelessness. Only time will tell, but this is what my heart is telling me.
