Imagine 2 blockchains processing the same amount of transcations. Now Chain 1 is running with ringsignatures and Chain 2 is not.
Now lets say that every year 500 GB of transaction data gets produced and no blockchain pruning and shrinking is available.
After 1/2/3/4/5 years
Chain 1: 750GB/1.5 TB/2.25TB/3TB/3.75TB
Chain 2: 500GB/1TB/1.5TB/2TB/2.5 TB
And this is under the best case scenario that ringsignatures only produce 50% bigger tx. This number can be higher!

Will a 110gb blockchain on full nodes really matter by 2019, when everyone is sporting 40tb drives? By direct comparison: Bitcoin's blockchain takes up 0.5% of today's 4tb drives, and comparably Monero would take up 0.275% of 2019's 40tb drives. In other words, disk space and Internet capacity is rapidly outstripping potential blockchain growth.
Ring signatures provide cryptographically untraceable and unlinkable transactions for a small sacrifice in blockchain storage in a world where disk space is not at a premium.
Sorry to spoil it for you, but most people do not have money to afford a 1TB thumb drive nor a 6TB HDD. In my country I rarely see people who have a 1TB HDD or higher (excluding myself). How do you plan to have a wider adoption? Although you never know, we might have 40TB drives we might still be stuck with the current limitations (look at batteries - minor/none improvement for years).
There are other ways to provide untraceable and unlinkable transactions. While ring signatures might bloat the blockchain a bit, they could do for now I guess.
On the flipside, those people will never ever have the cash to run a DRK Masternode where u need 1000 coins, i consider that a real issue as you need them for mixing, wheres Monero runs totally passive.
Oh then you understand the issues in areas where people are poor. You must realize that not all of them are able to use web wallets (not enough knowledge related to technology overall.
I dont get your point, its no difference to use a Liteweight wallet or a Fullwallet - both can look and feel exactly the same. And without Internet connection you can´t use cryptocurrency anyway - or well you could make an offline Monero transaction and bring it to someone with internet i guess - but have fun doing that with an active mixer engine.
