You should care about it, inscriptions effortlessly crowding out monetary TXs erode the monetary properties of the Bitcoin network.

Also, I regret to inform you that your node is censoring plenty of valid TXs behind your back. The most obvious cases are TXs paying less than 0 s/vB or having an OP_RETURN over 80 bytes. These kind of filters are no different than the ones Knots is running. My understanding is that some of them can't even be turned off with configuration options.
