If exchanges disappear, the only way to convert existing forms of money into Bitcoin is by peer-to-peer transactions?

In simpler words, the only way to buy bitcoins and be a part of the Bitcoin system would be by buying from a private.

This is because it seems there is no direct way, apart from private transactions, to transform any existing form of money, fiat included, into bitcoins. There are only indirect ways, the most important being mining coins.

But mining has become a matter of big farms and has escaped the reach of the common citizen, in the sense that performing mining has become negligible and inconvenient for the common budget (do you confirm?).

So if exchanges disappear: at the very beginning of the chain, the only way to enter the Bitcoin space with what one already has in terms of money is to directly buy it from miners. This theoretically happens already but exchanges are much more influential than miners for reaching the common citizen.

What will happen if the exchanges reveal to fail one by one? We've already seen two big examples, Mt. Gox and FTX. I believe that if Binance would arrive at the same fate, centralized exchanges would see their definitive end.

What would be the next step to ensure an optimal way for people to join the Bitcoin network?

Or, there is another way to join Bitcoin, that is to produce goods and services and be paid in bitcoins.By the way, if anyone is looking for any services and goods and wants to pay in bitcoins, I would be ready to hear your offers.

EDIT: by "convert" and "transform" I mean change the form of one's money. So if I have say 1,000 dollars, i convert/transform it into 0.029 BTC ( at today's rates).
