You sell me your old bike for £10 because you are skint.
I buy a £1 pot of paint and give the bike a new coat.
I then sell you a new bike for £20 because you really don't want to be without one.
I have, in fact, sold you back your old bike and made made £9 profit.
You have only what you started with but have £10 less
What happened there is that someone earned £9 from
(a) the realisation that the bike could be renewed with a can of paint,
(b) from their dedication of time and skill to obtaining and applying the paint
(c) marketing the renovated product.
So actually your example is in part a brilliant example of capitalism in action, and a positive example rather than a negative one.
Too often these days we chuck stuff away because we do not have the skill or time to fix it ourselves, and other people charge so much for that skill and time it would be cheaper to buy a new one.
However your opening comment was that the bike was sold because the owner was skint. He later had the funds to retrieve the (renovated) bike for twice the money, so plainly it was only a temporary problem. Temporary cashflow constraints can be resolved with short-term loans. You may have heard of the Grameen Bank in Bangladesh, whose founder won the Nobel Peace prize, which provides the micro-finance needed for life and small businesses in that country. Over-regulation, or inappropriate regulation, of financial systems results in micro-finance in places like the UK either being unavailable to relatively poor people, or only available at very high interest rates (loan sharks). Heavy-handed regulation is often a dampener on economic activity.
