… 30 short tons to orbit would be 60000lb @ $20/lb = $1.2 million… fusion SSTO costs to orbit should be cheaper than that and with a vastly less expensive infrastructure.
My stated reservations about the viability of fusion SSTO will only be valid for the short term after the introduction of fusion powerplants… and even the most optimistic beanstalk is a long term project…
