There are a lot of coins with low fees. They just not so popular. Every coin creator has its own idea about good coin. I like how LTC works
The problem on using unpopular coin was volatility and liquidity available on the market. Most of trader preferred to use coin that price is not that volatile and they can easily convert it without worrying about high price slippage when you market order the coin that's why Bitcoin and other famous coin with high transaction fee is still in use up to date.
