No. You can look at historical data regarding increases in processing power, and network capacity, both at specific price points. You can also look at near term projections of both of the above.
1. Need to change Bitcoin protocol to explicitly disallow transaction low fees. Currently minimum fees is only set with parameter minrelayfee, but miner could include transaction with 0 fees on mined block.
It is not possible to prohibit transaction fees under any threshold at the protocol level. A business could for example privately send a transaction that pays a transaction fee of 0.01 btc to a mining pool, and privately receive a refund of 0.005 btc separately when this transaction confirms. Miners will not do this unless there are insufficient transactions to fill blocks that pay the minimum protocol-required transaction fees.
