I think that Saylor - via his bonds - will stop the Choo Choo. Bear with me:

High interest rates are not imposed by the market on the government; they are imposed by the central bank on the market, where the intention is to discourage lending and therefore cut inflation

As Strategy grows and the number goes up, their bonds will essentially be considered "risk-free". Saylor will offer higher yields than Treasuries and demand for Treasuries will fall..

This will have a similar effect as if the central bank had imposed high interest rates. Lending will be discouraged and therefore - unless the government fight very hard with massive public spending (UBI?) - inflation will stop and the value of USD might even increase!

Thoughts?
