If I understand it, an 83(b) election allows me to buy stock in the company at the (say) day of employment, and recognise that as income on the same day (ie I buy the stock as I join). Then there is some restriction on me selling it during my employment (not quite vesting but similar).
Which sounds sensible - but I may have misunderstood.
Overall it seems either people are trying to make a simple situation seem complex, or the (US?) tax code is set up badly.
