That is correct. Just increasing the block size limit is not a feasible long term solution. It is, effectively "kick the can down the road" and "let someone else later deal with it". Increasing the block size limit comes with a lot more consequences than you think it does and there is a whole lot more nuance to increasing Bitcoin's capacity than you think there is.
Could you list some of these consequences? I can think of the obvious reasons like
higher bandwidth and storage requirements, but maybe you have additional reasons why
increasing the blocksize is a bad idea.
Generally, I think that some of the big companies like Coinbase and Bitpay should have
introduced Segwit addresses by now. That would really decrease the current congestion on the
blockchain. Instead they are busy integrating BCH in their respective businesses...
