"We suggest they fund themselves by:
Charging a nominal or small percentage fee on each claim processed"
Arbiters are employees of the blockchain, like block producers. Why should block producers be paid out of inflation while arbiters charged extra fees on users to fund themselves?
Maybe they should be funded by directing part of block producer pay to arbitration fund.
Another option is to pay arbiters out of worker proposal fund.
