Simply put again.

lAck of context does NOT in any shape or form negate an anomaly. why is that so hard to comprehend. if the context does not fit and the anomaly exists then a NEW context is required. Science anyone? Context is what we know now. NOT everything and anything to infinity. Context is only interpretation ; not data. As time advances data techniques and tools give us the ability to understand free of agendas and prejudices. Frauds exist and can be perpetrated. data and investigative techniques can identify such way beyond what could be done in the past. Context is only ancillary to those investigations.

The stone exists. period. Is it of a timeframe (patina) and time measuring tools. Is the inscription accurate and reflective of the language timeframe and usage? if fraudulent then context is moot? if real then context has to be modified. Context however does NOT determine either.
