Fees for trading affect you basically in every sort of trading, and if you don't own much, those fees will affect you more.

Lower dividend income and profits

Well percentually you get same gains. If you invest less on something, expect less profits.
Lack of stock voting rights
Sure, but you don't have voting rights trading synthetic stocks either and those seem to be something for example binance wanted to offer. And it's not like you have voting rights with bitcoin, if you want something else then majority, you will just create a fork.

This shows how the game is rigged against those who don't have enough money to spend on investment.
This is a matter of perspective. If you want higher fluctuation and potential profits with higher risk, you need to invest small caps.
In that way your bag of value grows with the marketcap. If you want to buy something overvalued, your money will never be enough unless you are rich.
Some people frown at the fact that Bitcoin is being termed an investment because Bitcoin was created to be a currency. They feel Bitcoin might lose its nature as a currency if it continues being an investment. I don't agree with that, but I respect their opinions.
Bitcoin can be both a currency and an investment
I have used bitcoin more like a currency than a store of value or investment. I bought bitcoin and sold it for money when i needed money. I have bought and sold bitcoin up to 2015, then i stopped and found new ways to get it.
I can't really regret using it as a currency even though one time i remember ticket to public swimming hall costing 0.3 btc. I bought my tv with one bitcoin. It's now worth maybe $200
I don't have to to say that btc was way cheaper then. But i can't regret it as no one knew how high it would rise. So i keep using it to buy and sell.
