If enough care about this that can and will do something about it (making formalization easier for the average author), that happens over time. Today there's a gap, and in the figurative tomorrow, said gap shrinks. Who knows what the future holds? I'm not discounting that the situation might change.
Its super easy to change imho: one could make a cryptocurrency, using PoT: Proof of Theorem, as opposed to just proof of stake or proof of work.
What do Bitcoin etc. actually prove in each block? that a nonce was bruteforced until some hash had so many leading zero's? Comparatively speaking, which blockchain would be more convincing as a store of value: one that doesn't substantially attract mathematicians and cryptographers versus one that does attract verifiably correct mathematicians and cryptographers?
Investors would select the formal verification chain as it would actually attract the attention of mathematicians, and mathematicians would be rewarded for the formalization of existing or novel proofs.
We don't need to wait for the magic constellation of the planets 20 years from now nor wait for LLM's etc to do all the heavy lifting (although they will quickly be used by mathematics "miners"), a mere alignment of incentives can do it.
